Replying to 191919:
% ffmpeg -aaa bbb ffmpeg version N-54349-g714aacc
The current version is 53346, and git doesn't know about 714aacc so I suggest you test FFmpeg first.

This is what I got by running OS X's sample utility. It looked like there was an infinite loop in the code to match the codec.
Sampling process 990 for 10 seconds with 1 millisecond of run time between samples
Sampling completed, processing symbols...

Could you elaborate on the strange version information that your executable provides? Where did you get the sources from?
comment:7 by , 12 years ago
As said the version number is too high and git does not know 714aacc indicating that you are not using (vanilla) FFmpeg from source.ffmpeg.org.
comment:8 by , 12 years ago
I have recloned ffmpeg source from git://source.ffmpeg.org/ffmpeg (I guess SourceTree messed up the version number). The problem is still reproducible.

The output of OS X's sample utility is identical as before.
Since Apple doesn't provide gcc as their compiler, I had to switch to the clang's svn version.

Error splitting the argument list: Option not found
So the conclusion: it was a bug of Xcode compiler. I will commit a bug to their bug tracker and will try to find which caused the problem.
Thank you all guys.

| Component: | FFmpeg → avformat |
|---|---|
| Keywords: | md5 regression added |
| Reproduced by developer: | set |
| Status: | new → open |
Some information:
The following configure line allows to reproduce the problem
$ ./configure --disable-everything --enable-muxer=framemd5,md5 --disable-asm --disable-yasm --disable-optimizations --extra-cflags=-O2 && make ffmpeg
The problem disappears if libavformat/md5enc.o is compiled with -O1
Reimar suggested to rename the .class_name of the framemd5_class (which works), he has sent a patch.
Different backtraces possible:

for help on using tickets.
I think this is a bug in the Mac LLVM. Can you try with another compiler?
