I've looked a bit at the semantics of output_clone (in
/usr/share/dejagnu/framework.exp), and the only way I could think of how
that would happen for you is if the output somehow starts with a keyword
like PASS/FAIL/WARNING/ERROR/etc. [ If you want to chase that difference
it could be useful to post a gdb.log/gdb.sum/stdout_stderr.log. ]
Anyway, the behaviour I'm seeing looks correct to me.

Ack, thanks for the review.
