[Bug middle-end/38200] [4.4 Regression] internal compiler error: in find_func_aliases, at tree-ssa-structalias.c:3905

[rguenth at gcc dot gnu dot org]

------- Comment #1 from rguenth at gcc dot gnu dot org  2008-11-20 15:15 -------
Invalid gimple:

(gdb) call debug_gimple_stmt (origt)
# STORES:  { foo_ptr }
foo_ptr ={v} (int (*<T4cb>) (void * *)) ptr.3_4;

produced by forwprop.  Probably caused by Jakubs patch

        PR middle-end/38140
        * tree-ssa-forwprop.c (forward_propagate_addr_expr_1): If
        propagating x = &a into *x = b, add a cast if not useless
        type conversion or don't optimize if another stmt would be
        needed.
