Can we do that?  I was under the impression that "(timeout)" was
special.  If we can, I'll add both cases - for the wrong debug info and
for some unknown failing output.  I'm tempted to mark such tests XFAIL
if we can obviously detect that the compiler is at fault; admittedly,
the test isn't perfect, but it's still better than the current state of
affairs...
