 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
 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:

 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.
