Hi,

fate-vsynth1-mpeg2-422 is broken after this patch (commit 17a59a6).

configuration: --prefix=/usr --libdir=/usr/lib/x86_64-linux-gnu --shlibdir=/usr/lib/x86_64-linux-gnu --disable-static --enable-shared --enable-gpl

It works with option --disable-ssse3

Below is the info for my CPU

$ cat /proc/cpuinfo | grep 'model name' | head -1
model name      : Intel(R) Core(TM) i5-1035G1 CPU @ 1.00GHz

Thanks
