go pegs cpu, does not return (gcc-go)

I'm not a go expert, just trying to build some other software which uses go. On both 14.2 and current, running a simple go example pegs one CPU at 100% and does not return (even after hours of running).

Example

$ cat test.go
package main

import (
        "os"
)

func main() {
        os.Exit(0)
}

$ /usr/bin/go run test.go

This returns immediately on x86/x86_64, but has the problem described above on arm. Has anyone else noticed this?

"go" has been broken since its inclusion. I have no idea what is wrong with it. If you find out, let me know!
I've looked at this a few times and looked at Debian and Fedora for patches but there were none that had any relation to "go", so perhaps the problem is elsewhere.

I'll confirm it's broken, in both SMP and UP, on ARM but not on x86. "go do anything" even fails to parse. The failure is very early: the standard libpath libraries load, then it deadlocks in an infinite loop.

I've been experimenting with gcc-go and now I get something more useful.
Does the test code actually work properly elsewhere?

Yes it does. *shrug*

It's still broken here on ARM, but not on x86.

since this thread is about gcc-go.... after last upgrade-all

gcc-go-8.2.0-arm-2.txz is there but gcc-go-8.2.0-arm-2.txz.asc is not

Thank you Stuart.

Thanks. Fixed.

Try upgrading to gcc-go version 9. It's back in the main tree and seems to work.
14.2 won't get a fix though as I've no idea what the problem was - it's just started working with gcc-9.
