Your gdb dump is not very useful because it fully miss names in
backtrace. All I can say from disassembler is that is
x264_memzero_aligned_sse2 and it gets not 16-byte aligned pointer
which can't be so this probably miscompilation because all 3 places
where memzero_aligned used it get 16-byte aligned dest. So either
compiler didn't honor align directives or dunno.
