I think the above is a different problem.  The explosion is most likely
a problem with exception edges in the gcse pass.  Try `-fno-gcse'.  This
also appears in the tFile.cc libio test.

The pa port uses sjlj exceptions via __builtin_setjmp/longjmp.  A
nonlocal goto label is used for the target of the longjmp.  The flow
analysis assumes that an "exception" could jump to any label in the
procedure rather than just the label associated with the exception
region.
