--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2012-08-13 15:35:11 UTC ---
Segfaults in
4837 gfc_type_compatible (gfc_typespec *ts1, gfc_typespec *ts2)
4838 {
4839 bool is_class1 = (ts1->type == BT_CLASS);
4840 bool is_class2 = (ts2->type == BT_CLASS);
...
4853 else if (is_class1 && is_class2)
4854 return gfc_type_is_extension_of
(ts1->u.derived->components->ts.u.derived,
4855
ts2->u.derived->components->ts.u.derived);
The problem is that ts2->u.derived->components == NULL.
