Segfault converting m2t file with ac3 audio track when number of audio channels changes.

Description

When converting an m2t file with a 5.1 channel ac3 audio track to mkv, ffmpeg segfaults when the number of audio channels in the source stream changes. The source stream was recorded from DVB and during an ad break changes from 5.1ch audio to 2ch audio (and presumably back again at the end of the adverts). The command line used was:

ffmpeg -y -i Summernats\ 2011.m2t -pass 2 -acodec ac3 -ab 512k -vcodec libx264 -vpre slow -vpre baseline -threads 0 -vsync 1 -b 2048k -bt 2048k -nr 400 -aspect 16:9 -s 1440x1080 -sn Summernats\ 2011.mkv

I would upload a sample but the original file is 6.9GB and I'm not sure how far into the file the switch occurs (the status line is overwritten by the segfault data as shown above).

Looks critical to me, work-around is to use -acodec ac3_fixed.

Reproducible with

$ make fate-acodec-ac3_fixed
$ ./ffmpeg -i tests/data/acodec/ac3.rm -acodec ac3 -ac 6 out.ac3

This is a regression because the following works as expected:

$ ./ffmpeg -i tests/data/acodec/ac3.rm -acodec ac3_fixed -ac 6 out.ac3

$ valgrind ./ffmpeg_g -i tests/data/acodec/ac3.rm -ac 6 out.ac3

I don't get a backtrace with above sample, but with the following:
