You are right, this does not fail with a gcc-3.4.0 tree.  It does
however fail with gcc-3.4.1.  This was "fixed" by a C front end patch by
Roger Sayle in June.  See PR 14649.

I am not sure whether the regression tester is giving us any useful info
in this case.  There are too many different bugs interacting in
different ways to be sure.  Since mainline in February did not have
Roger's June C front end patch, the failure found by the regression
tester might be a different one than what we have now.
