It's a 32bit build, maybe it's not reproducible with 64bit build? I'm compiling now ffmpeg with --enable-debug.
comment:3 by , 9 years ago
so I get the same backtrace with the git head
maybe someone can test if this is reproducible on linux 32bit

Could you try to reproduce the crash with this binary?
http://johnvansickle.com/ffmpeg/builds/ffmpeg-git-32bit-static.tar.xz
Note:
See TracTickets
for help on using tickets.
Can not reproduce here, could you compile your ffmpeg with debug symbols on?
