Even if you could, the compiler should not crash, "period". Though,
this is a lower-priority kind of bug (in most peoples' minds) than
one in which it doesn't crash but generates wrong code.
In any case, a code fragment is unlikely to help anyone find the
source of the problem. Please follow the directions for reporting
bugs (in the g77 docs should do fine), especially the part about
sending the complete source code. This is a classic case where
that's necessary, at least under normal circumstances (though we
perhaps have a few on this list who can figure out the bug just
by looking at the error message, so we might get lucky ;-).
