Comment 1 Andrew Pinski 2005-05-18 20:50:54 UTC 
This should been fixed by:
2005-05-18  Jeff Law  <law@redhat.com>

        * tree-ssa-forwprop.c (forward_propagate_addr_expr): Do not
        propagate an ADDR_EXPR if the definition and use sites are
        in different EH regions.
Comment 2 Andrew Pinski 2005-05-18 21:12:30 UTC 
Yes it was fixed by that patch.
