Thank you for spotting it. The issue is that randomize_buffers() writes 4 bytes at a time. I think the proper fix is to change randomize_buffers() to not write past the end of the buffer. It would be even better to move randomize_buffers() to checkasm.h or checkasm.c so it doesn't have to be copied around so many times. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
