Description
Summary of the bug: FFMPEG Crashes when converting AC3 to AAC with DRC enabled. This is with the newer builds.
The last working build is N-40640-g5edd4fc, no issues.
The source file is too big to attached (this happens at about the 43 second mark).

The bare minimum command I've been able to use to replicate this issues (both async and threads needs to be used with drc for ffmpeg to crash).

I dont' have access to building GDB unfortunately so theres now way for me to provide a backtrace.
But here is what I've got from Visual Studio debugger

comment:6 by , 13 years ago
The crash is fixed, but audio output is broken after channel count change if -async 1 was used.

locally fixed, will be in my next git push
Note:
See TracTickets
for help on using tickets.
Backtrace etc. missing, please see http://ffmpeg.org/bugreports.html
Is the crash also reproducible with -acodec aac -strict experimental?
