--- Comment #13 from Jason A. Donenfeld <jason at zx2c4 dot com> ---
The GCC-bug side of things seems to be a bad optimization caused by weird
register allocator performance. That's being tracked here:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D103252

The .o that gcc creates for both the avx512 case and the non-avx512 case bo=
th
have the same relocation type:

000000f0 R_386_TLS_GOTIE   __libc_tsd_CTYPE_B

That makes me suspect that the problem isn't with gcc but is with something=
 in
binutils -- the assembler or the linker or something called later on.

Either way, I'll attach the preprocessed source and assembly as requested.
