I don't know what is happening here.

The way this test works is that the file gcc/testsuite/go.test/test/index.go
and gcc/testsuite/go.test/test/index0.go are compiled together, producing a
file index0-out.go.  Then that file is compiled and run.  It is expected to
exit 0 with no output.  When I run that file on my laptop, it takes 0.2
seconds.  Clearly something is going very wrong on your systems.

I've attached that file.  You should be able to compile it using gccgo as
usual.  Perhaps you can use that to debug where it is failing.
