@neheb: I thought we had x86 tests running in our Actions workflows now? Is this a different configuration that you'd like to enable?

It might be easiest to just delete this test if it continues to cause problems. It's a regression test for an old bug that would get caught very quickly by OSS-Fuzz if it were accidentally reintroduced.

x86 under Windows. Note that I enable UBSAN here.

auto p = fs::path("/proc/self/exe");

is enough to trigger that error. Some glibc or libstdc++ bug. I give up.

Is that on arm32?
