This FFmpeg was build on Ubuntu 10.04.
We are demux a m4a file which is actually corrupted and its not played by iTunes or VLC. FFmpeg 0.8.6 was able to demux correctly but FFmpeg Trunk is crashing for the same file.
We are also providing a patch which solves this problem."	defect	closed	important	avformat	git-master	fixed	mov crash SIGSEGV apic id3	donmoir@…			1	0
