He said in the Gentoo bug:

> Note that 16-byte stack alignement is required by i386 psABI so every such
> crash signifies a violation of this ABI (these violations now started to
> bite since newer GCCs do make use of this requirement to generate code with
> SSE instructions in things like glibc).

I don't know what CFLAGS you use on Gentoo but rebuilding glibc with any flags
that enable SSE should do the trick. Then do just about anything with Java like
"jar tf" on some archive. I didn't see it with -march=pentium-m but I have an
AMD Ryzen, which may behave differently? Using -march=native will probably
trigger it.
