https://github.com/golang/go/issues/51787 maybe?
I'm having similar issues and think it is related to https://bugs.gentoo.org/840311#c14.
(In reply to Sam James from comment #3) > https://github.com/golang/go/issues/51787 maybe? I tried the patch (https://github.com/alpinelinux/aports/commit/866f2e147cfbb06eec9179e7323be6d2f82b5290) which is suggested in the issue. It applies but it does not work out. Also tried buildling with GOEXPERIMENT=noregabi emerge -1 go FEATURES="-sandbox -usersandbox“ emerge -1 go or using sandbox-2.25 as suggested in the bug motori pointed to but it didn'T work out either.
confirmed, just hit this on timberdoodle what's interesting is that ANYTHING compilied by go will segfault, even go-md2man.

I suspect kernel is to blame and I think it's the pwnkit argv fix that triggered it. timberdoodle was running 5.15.32-gentoo-dist-hardened until recent update and go/docker was fine I've updated to 5.15.63-gentoo-dist-hardene and started noticing segfaults. pwnkit fix landed to 5.15.y here https://github.com/gregkh/linux/commit/1290eb4412aa0f0e9f3434b406dc8e255da85f9e and was released as 5.15.33 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.15.33 I still have old kernel around, so it's easy to test by booting to it.
confirmed, go still works on 5.15.32 on ppc64be
found upstream fix https://github.com/golang/go/commit/823e5d8afaaf9fff0cc2ab04e7fc0a62b1023c3e go1.19.1 is fine and contains the fix. so we'll need a new cut of go-bootstrap and get rid of 1.16.6
