ICEs in simplify_subreg called from expand_debug_expr. Seems this is Fortran
FE's fault, but I think we should both fix up Fortran FE and make
expand_debug_expr more robust.

------- Comment #1 from jakub at gcc dot gnu dot org 2010-02-24 19:51 -------
Created an attachment (id=19952)
--> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=19952&action=view)
gcc45-pr43166.patch
Patch that both robustifies cfgexpand and hopefully fixes Fortran FE common
block handling.
