Can you rebuild glibc with debugging information and capture another backtrace? Given ssse3, a fix would be low-level; so, more debugging information is needed.

Yes! Wait... As a workaround, removing ssse3 flag works. gdb --args ffmpeg -i '/home/de/large/media/test media/FULL_HD_porsch.mp4' -threads 4 -vcodec libx264 -an /tmp/test.mkv GNU gdb (Gentoo 7.6.2 p1) 7.6.2 Copyright (C) 2013 Free Software Foundation, Inc.
