Malloc-ed regions are 8-byte aligned in x86 Linux. This causes some SSE code to do unaligned accesses, causing SIGSEGV.

You could use alignas to align the buffers used by SSE code.

alignasdoes not align the dyanmically allocated buffers. We need an aligned allocator... https://gist.github.com/donny-dont/1471329

@yvt is this issue still valid?

yvt commented 7 years ago

As far as I can see from the source code, It's still valid.
