Spent a fair bit of time reducing the problem to something triggering the problem in isolation. This is somewhat scary - I'd be quite surprised if this were the only place triggering the bug. And I suspect that it doesn't actually require -mtune=skylake, but I'm not sure. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=106590 Greetings, Andres Freund
