[FFmpeg-devel] [PATCH] Adding av_abort() : adding custom handlers for abort().

Historically, we had issues with the abort() within libavcodec/vlc.c  alloc_table(), but possibly those are now fixed.

We had a different behavior on Windows back then.
Now that we can compile ffmpeg with VisualStudio (instead of cross-compiling with gcc on Linux), we will try to re-go the route of SIGABRT signal handler, and see if we got more success now that we have the same C runtime.
(We had a custom handler to create a "full mini-dump" with dbghelp.dll)

Thanks to make me realize our problem (and solution) is now potentially obsolete.
