The changes to the Go frontend are fine, but they need to be applied to
the master repository for the Go frontend.  I can take care of that when
you are ready to commit the patch.  Note that changes to the files in
gcc/go/gofrontend do not get ChangeLog entries.

I'm sure it has nothing to do with your patch.  I have not seen other
people report this, though.  Some of the tests in the Go testsuite use a
lot of threads, like thousands.  It's possible that that is running into
some limit on your machine.  This would be particularly applicable if
you are running the testsuite with make -j.
