On riscv, trying to emerge any version of dev-lang/go with PORTAGE_SCHEDULING_POLICY=idle set in make.conf results in an infinite hang on "Building Go toolchain1". Does not affect other architectures. This affects all versions of go. Tested bootstrapping from dev-lang/go-1.19.4, dev-lang/go-bootstrap-1.19.1.

I'm updating the title here because despite unsetting PORTAGE_SCHEDULING_POLICY=idle globally, I ran into this issue again with dev-lang/go-1.20.2. After working through everything in FEATURES, I identified that it requires FEATURES=-usersandbox. This works correctly even when PORTAGE_SCHEDULING_POLICY=idle is set. Have no idea what's going on with this - maybe kernel changes?
I'm using amd64 and yes, it does hang on "Building Go toolchain1 using /usr/lib/go-bootstrap"
It was hanged at "/usr/lib/go-bootstrap/bin/go build -o cmd/dist/dist ./cmd/dist" but I was be able to pass it by removing and installing go-bootstrap package. now it hangs on bulding toolchain.
I tried emerging go with FEATURES=-usersandbox and it built succesfully.
I have exactly the same problem on my x86_64 freshly installed system (Linux minion 6.1.19-gentoo-x86_64 #1 SMP PREEMPT_DYNAMIC Wed May 10 14:59:39 MSK 2023 x86_64 AMD Ryzen 9 5900HX with Radeon Graphics AuthenticAMD GNU/Linux). Same approach of fixing ("-usersandbox") also helps. Although in my case it's dev-lang/go-1.20.3. Got this problem with the initial installation using both versions of dev-lang/go-boostrap (1.18.6 and ~amd64 1.19.1), have the same problem with the installed go's toolchain afterwards. Thus it's not just riscv, but at least also x86_64.
I would like to report the very same problem on ~amd64. Actually in last April, I first experienced this problem. Yet due to my lack of experience and no compilation output (I turned them off), I have no idea what was wrong. Go is being compiled on my machine with a strange cpu load (~1.27, while I gave 12) and from output of htop, only a single core was working. In the following versions of go, this problem appeared from time to time but since I see no one reported it (I once skimmed through bugs of dev-lang/go), I assumed it was my problem perhaps. Even now none of the gentoo users around me has ever experienced this problem. For now, I used `FEATURES=-usersandbox emerge -av1 dev-lang/go` to build it, as suggested in comment 4 above. I'd like to add any further information if needed. Thank you :)
This issue seems solved with new go version 1.21.1 amd64. I updated the package without any tinkering.
See also: https://bugs.gentoo.org/912072 Not fixed with 1.22. Definitely sandbox- and/or runtime-initialisation related.
