Severity: important

Control: affects -1 src:winff
Hi,
Just noticed that winff's autopkgtests fail on armhf because ffmpeg
receives a SIGBUS.
The failing command is:
> /usr/bin/ffmpeg -i test.avi -vcodec flv -f flv -r 29.97 -vf scale=w=320:h=240
> -aspect 4:3 -b:v 300k -g 160 -cmp dct -subcmp dct -mbd 2 -flags +aic+mv0+mv4
> -trellis 1 -ac 1 -ar 22050 -b:a 56k -y -t 1 test.flv
Where test.avi can be obtained from the winff source package:
https://sources.debian.net/src/winff/1.5.5-1/debian/tests/test.avi/

Note the backtrace is taken just before the SIGBUS because
ff_diff_pixels_armv6 reuses lr which makes obtaining a backtrace
difficult otherwise.

It appears that the 3rd argument (r2 / src2) is misaligned which causes
the SIGBUS:
> (gdb) info reg

At this point I stopped looking into the bug for now.
