Hi.
I think I found a bug.

I am using gollvm - my "release" build could be found here

Sorry for being slow , cycles are very scarce at the moment.

I'll take the bug but can't promise when I can have a closer look.
PRs welcome.

@skalle , what do you require (to reproduce the bug)?
I am re-compiling gollvm, right now - the recent archive with binaries could be obtained from here.

Let me know what you would require from gollvm's "debug" build, what level of verbosity would you require.

I do see these values defined in gccgo's syscall package, in the generated sysinfo.go file.
