"Considering that it happens only on Ryzen and with multiple GCC versions and that the first post in this Gentoo forum thread shows segfaults in bash (not gcc) it looks rather like a CPU bug manifesting itself under load. " Well, maybe. x86 is obviously a large target, and there are definitely weird corner cases and stuff that, while often not legal, just happen to work on intel and not amd (or vice versa) I'd still bet on that before i'd bet on hardware bug. Certainly the hardware bugs occur, but software tends to be buggier :)
