Description

Summary of the bug:

ffmpeg segfaults on ANY execution under macOS 10.15 "Catalina" (Developer Preview 19A526h).

For context (don't know if it's related or not), this is the first macOS release that will no longer run ANY 32-bit code.

Attempted this on tags 4.1.3, 4.1.4, and 4.2; latest master (commit da8936969fe695a042282d5686e12227745d299a as of this writing). Same compilation commands do not result in segfault in macOS 10.14.6 "Mojave".

How to reproduce:

In an attempt to pare down the options to the smallest possible set in order to identify the source of the bug, I've got this:

$ MACOSX_DEPLOYMENT_TARGET=10.15 \
LIBFFI_CFLAGS=-I/usr/include/ffi \
LIBFFI_LIBS=-lffi \
GLIB_CFLAGS="-I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include" \
GLIB_LIBS="-lglib-2.0 -lgio-2.0" \
CFLAGS=`freetype-config --cflags` \
LDFLAGS=`freetype-config --libs` PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:/opt/X11/lib/pkgconfig \
./configure \
    --arch=x86_64 \
    --cc=/usr/bin/clang \
    --disable-all \
    --disable-everything \
    --disable-stripping \
    --enable-debug=3 \
&& \
make -j$(nproc) && \
make install

(tested WITH and WITHOUT the environment variables preceding ./configure)

Results in:

$ ffmpeg 
Segmentation fault: 11

Based on some searching, I ran the following in an attempt to debug further.

$ lldb $(which ffmpeg)
(lldb) target create "/usr/local/bin/ffmpeg"
Current executable set to '/usr/local/bin/ffmpeg' (x86_64).

Bug reporting details

​http://ffmpeg.org/bugreports.html references gdb, which I'd be happy to install, but based on my reading it sounds like llvm, clang, and lldb have replaced gcc and gdb (at least on macOS).

This set of compilation commands does not appear to produce ffmpeg_g. Could not find any matches using:

find . -type f -name "*ffmpeg_g*"

Valgrind does not appear to support current macOS (10.14) nor the latest dev preview (10.15).

I am not a C developer, but I am happy to provide any additional information about my environment if instructions can be provided.

comment:2 by Ryan Parman, 5 years ago

I've continued to poke at this over the last few weeks, and discovered that I had unintentionally disabled core dumps on my system. I also realized that I was running an older version of the binary that wasn't tied to my current compile. I'm a dumbass.

So…

  1. Today I pulled down the latest master (commit cc78783ce5e8837d4f4ca43eedf2d299651e65ff).
  1. I'm running the latest developer beta of macOS "Catalina" 10.15 (19A546d)
  1. I updated the compile command (trying to find the simplest compile that results in the issue), as follows: 
$ MACOSX_DEPLOYMENT_TARGET=10.15 \
LIBFFI_CFLAGS=-I/usr/include/ffi \
LIBFFI_LIBS=-lffi \
GLIB_CFLAGS="-I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include" \
GLIB_LIBS="-lglib-2.0 -lgio-2.0" \
CFLAGS=`freetype-config --cflags` \
LDFLAGS=`freetype-config --libs` PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig:/usr/lib/pkgconfig:/opt/X11/lib/pkgconfig \
./configure \
    --arch=x86_64 \
    --cpu=native \
    --cc=/usr/bin/clang \
    --disable-htmlpages \
    --disable-podpages \
    --disable-txtpages \
    --disable-stripping \
    --enable-debug=3 \
    --enable-small \
&& \
make -j$(nproc)

This resulted in ffmpeg_g in the local directory. After re-enabling core dumps (with ulimit -c unlimited), I ran it with lldb:

$ lldb ./ffmpeg_g
(lldb) target create "./ffmpeg_g"
Current executable set to './ffmpeg_g' (x86_64).
(lldb) r --help
Process 41569 launched: '/Library/WebServer/Documents/ffmpeg/ffmpeg_g' (x86_64)
Process 41569 stopped
* thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS (code=EXC_I386_GPFLT)
    frame #0: 0x00007fff67bfb316 libdyld.dylib`stack_not_16_byte_aligned_error
libdyld.dylib`stack_not_16_byte_aligned_error:
->  0x7fff67bfb316 <+0>: movdqa %xmm0, (%rsp)
    0x7fff67bfb31b <+5>: int3   
    0x7fff67bfb31c <+6>: nop    
    0x7fff67bfb31d <+7>: nop    
Target 0: (ffmpeg_g) stopped.

…which is pretty much the same as last time. I ran the binary again to generate a core dump.

$ ./ffmpeg_g
Segmentation fault: 11 (core dumped)

I then loaded the core dump into lldb:

$ lldb -c /cores/core.41724 
(lldb) target create --core "/cores/core.41724"
Core file '/cores/core.41724' (x86_64) was loaded.

​http://ffmpeg.org/bugreports.html appears to be outdated, and should probably be updated for llvm by someone who understands this stuff. But here was what I was able to figure out:

(lldb) bt
* thread #1, stop reason = signal SIGSTOP
  * frame #0: 0x00007fff67bfb316 libdyld.dylib`stack_not_16_byte_aligned_error

The disass $pc-32,$pc+32 command listed doesn't work as expected in lldb. I was able to find ​https://lldb.llvm.org/use/map.html where I was hoping to be able to convert the command into something functional, and this is where I ended up. Please let me know if you need me to run a different command instead.

(lldb) disassemble --pc --count 32

I am downloading the latest developer beta of Xcode right now. I'll try again once I get it installed to see if I learn anything new.

Sorry -- my ad-blocker prevented me from seeing the comment section in Trac. Just seeing this now after posting a new comment that I couldn't see.

In both my original ticket and today's update, I've started off with git pull origin master -- as I wrote in my initial message:

Now that I've seen your comment, I've run make clean && ./configure && make -j$(nproc) ffmpeg. Running in lldb…

Please test with --disable-asm - since the backtrace and the disassembly contain no information related to FFmpeg, you don't have to repeatedly post them.

[...] since the backtrace and the disassembly contain no information related to FFmpeg, you don't have to repeatedly post them.

That's fine. Just trying to be a good citizen by following the bug reporting instructions as best as I can. Compiling again with:

make clean && ./configure --disable-asm && make -j$(nproc) ffmpeg

Taking your words literally, removing thebt and disassemble --pc --count 32 from my response, but keeping register read --all. (I'm not a C developer, so if you need me to do something different, please be specific and I'm happy to provide information.)

Does the following configure line change anything?
$ configure --disable-everything --disable-asm --disable-vdpau --disable-vaapi --disable-zlib --disable-pthreads --disable-bzlib --disable-ffnvcodec --disable-audiotoolbox --disable-videotoolbox

Looks a little bit different...

make clean && ./configure --disable-everything --disable-asm --disable-vdpau --disable-vaapi --disable-zlib --disable-pthreads --disable-bzlib --disable-ffnvcodec --disable-audiotoolbox --disable-videotoolbox && make -j$(nproc) ffmpeg

I don't know if the following works on your system but it is my last suggestion to delimit the cause of the issue.

$ configure --disable-everything --disable-asm --disable-vdpau --disable-vaapi --disable-zlib --disable-pthreads --disable-bzlib --disable-ffnvcodec --disable-audiotoolbox --disable-videotoolbox --extra-ldflags=-static

comment:11 by Ryan Parman, 5 years ago

Trying again…

make clean && \
./configure --disable-everything --disable-asm --disable-vdpau --disable-vaapi --disable-zlib --disable-pthreads --disable-bzlib --disable-ffnvcodec --disable-audiotoolbox --disable-videotoolbox --extra-ldflags=-static && \
make -j$(nproc) ffmpeg

Output:

gcc is unable to create an executable file.
If gcc is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

It seems the 10.15 toolchain turns on "-fstack-check" by default for Clang, like some Linux distributions do. You can see that ​here:

Stack checking is on by default on all platforms to prevent memory corruptions. (25859140)

Some discussion ​here traces it back to AVX, although turning off AVX ("--disable-avx") didn't seem to help building FFMPEG. (Nor, as skyzyx saw above, did turning off ASM entirely.)

Accordingly, adding "-fno-stack-check" to "CFLAGS" - f.ex., by '--extra-cflags="-fno-stack-check"' when configuring works around the problem and builds a functioning FFMPEG.

Don't quite know what that means for us. I imagine having stack checking on is desirable, but there's at least a workaround while the source is further investigated.

@zwaldowski: This allowed me to build the latest Git master on macOS 10.15 "Catalina" in a working state. Thank you.
