Hello hikaru, (I have tried to split the browser issue into a different bug #783293.) When libav is built with this 3 attached changes then vlc and mplayer2 are not crashing anymore. This would need some more tests as I had only my qemu VM (which was way too slow) with one video file inside.

Hello hikaru, additional to the patch above it looks like there is also a flaw in debian/confflags: --- libav-11.3.orig/debian/confflags2015-01-17 18:25:07.0 + +++ libav-11.3/debian/confflags 2015-04-22 22:35:12.616951338 + @@ -180,7 +180,7 @@ shared_build_confflags += --enable

Hi Bernhard, I have run your gdb examples on the K6-2 now and came to the same result for vlc: Program received signal SIGILL, Illegal instruction. [Switching to Thread 0xb0fd4b40 (LWP 1001)] 0xaf19da49 in mid_pred (c=0, b=0, a=0) at /build/libav-H9AQHK/libav-11.3/libavcodec/x86/mathops.h:77 77
