Looks like here the tests might be run on a different go version than they're built on?

I can send a patch, but can anyone confirm that's the case or is something else going on?

Tycho, I think the issue is that you were looking for the "runtime.Version" to start with "go1.2" I'm guessing that GCC-go uses a different version string. Something like gccgo-1.2. I don't really know what it would be. But it isn't that we compile on one and use another, just that we use a different *compiler* and that didn't match your original check.

The gccgo version string always has "xgcc" in it
    $ go version
    go version xgcc (Ubuntu 4.9.3-0ubuntu4) 4.9.3 linux/ppc64le
