You have to use ffmpeg_g which contains debugging symbols.
comment:5 Changed 5 months ago by cehoyos
Please compile current FFmpeg, a default compilation with ./configure && make contains a debug binary.

http://rogerdpack.t28.net/incoming/ffmpeg_distros/ffmpeg-distro-static-2013-01-11-969e75eb80dad51481152f868dafa802579a19aa.debug_symbols.7z may be a build you could use with debug symbols
but...why are you using ctrl+c here, instead of 'q'? Are you saying that ctrl+c should act like the q key does? What is an example command line that causes the behavior?
comment:7 Changed 5 months ago by ramitbhalla
same thing, i started out with ffmpeg using ctrl+c like any command line program. just that in the newer releases it crashes, where as earlier it used to quit like 'q'. i can test it when I get back otherwise rogerdpack, if you have a debugger setup, just run any ffmpeg command and while it's runnign press ctrl+c and you can trace the stack.
comment:8 follow-up: ↓ 9 Changed 5 months ago by ramitbhalla
Not really sure how to use the debug symbols here since I don't have the source code:
Here's the stack I get:

Replying to ramitbhalla:
Not really sure how to use the debug symbols here since I don't have the source code:
You will need the source code to give gdb the possibility to provide a useful backtrace.
comment:10 Changed 5 months ago by ramitbhalla
I don't have GDB, I use Visual Studio - an to be honest not the best at it.
I can only request someone like rogerdpack to replicate it (very very easy) and see where it bugs out.

if it worked before, which change broke it ?
comment:12 Changed 5 months ago by ramitbhalla
