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

Code:
$ 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.
