If possible, provide a recipe for reproducing the error.

run all.bash

A complete runnable program is good.
A link on is best.

I've re-titled this issue, since it seems to only concern a test in the runtime package.

Note that to build Go, you can simply use make.bash instead of all.bash - there's no strict need to run the tests to build Go.

Could you try 1.11 or tip? This should have been fixed by moving to libc calls instead of raw system calls.

Sorry, you did do that. 1.9 was just the bootstrap compiler.

Could you try patching in and see if that fixes your issue?

If it does, we should get this fix into 1.11.
