Replying to [comment:1 cehoyos]:
> Is the crash only reproducible with -acodec libfaac or also with -an ?
> Is -vcodec libx264 needed to reproduce the crash or is -vcodec mpeg4
sufficient?

input file?
No specific sample is needed. The crash happens with any input file,
including streaming source (udp in my case).
Yes, it crash without "-movflags frag_keyframe" too. But IMHO "-movflags"
key is required for ISMV, fragmentation parameters should be somehow
passed to muxer.
Same behavior with "-an" and "-acodec libfaac".
As I know, ISMV may contain only h264/vc-1 for video and aac/wma for
audio. Any way, I tried both libx264 and mpeg4, both resulted in crash.
In the same time, I must mention that the crash is muxer specific. Usage
of FLV muxer with the same input parameters was successful. The following
command was used for FLV:
ffmpeg_g -y -i /home/test/Kak_ukrast_million.avi -c:a libfaac -c:v libx264
-movflags frag_keyframe -f flv /home/test/Kak_ukrast_million.flv
