strace of `go-7 env`
The command go-{5,6,7} (for version 5.4.0, 6.4.0, 7.2.0) all run infinitely
even without any arguments passed (i.e. simply calling `go-7`) on sparc on
linux, and utilizes entire processor thread to 100%. The strace is attached.
I'm using Gentoo with Linux kernel 4.9.49 (Linux sparc 4.9.49-gentoo-r1 #2 SMP
Sat Oct 7 04:48:20 CST 2017 sparc64 sun4v UltraSparc T2 (Niagara2) GNU/Linux).
The userland is 32 bit if that matters. Below is `gccgo -v`.
$ gccgo -v
Using built-in specs.
