Comment 1:

It would be helpful to see the output of
cd $GOROOT/src/pkg/archive/tar
sh -x gotest
Thanks.

Comment 5 by aphax@hotmail.com:

I just wanted to note that despite already having that revision, the problem still
occurs. I can work around it by setting LC_ALL=C, as suggested on the CommonProblems
page.

Comment 6 by adam.lehenbauer:

This is still occurring for me; the LC_ALL=C workaround does not help.

The compiler, linker, etc are created and they seem to work but any program fails to 
run
