1412	ffmpeg crashes on win64 when decoding a dirac stream	jamal		"Summary: ffmpeg (mingw64 x86_64 GCC 4.7.0, yasm 1.2.0) crashes when trying to decode a dirac stream.
This however doesn't happen if i compile ffmpeg with the --disable-yasm option.
ffprobe and even ffmpeg with no output parameters run fine when reading the file and wont crash.

The command line i used was:
{{{
./ffmpeg -i bbb-tr1000.ts -vcodec zlib -an asd.mkv
}}}

And this is the sample i used: http://dirac.kw.bbc.co.uk/download/video/maybefinal/bbb-tr1000.ts

I'm attaching both the ffmpeg log file and gdb's output.
gdb mentions ff_add_rect_clamped_sse2 as the source of the problem, which might explain why disabling yasm got rid of the crash."	defect	closed	important	avcodec	git-master	fixed	dirac win64				1	0
