==8885== Invalid read of size 8 ==8885== at 0x4C2050: compare_type_rank (interface.c:474) ==8885== by 0x4C20C4: generic_correspondence (interface.c:905) ==8885== by 0x4C28B9: gfc_compare_interfaces (interface.c:986) ==8885== Address 0x98 is not stack'd, malloc'd or (recently) free'd At a glance, the code looks innocent. interface.c:474 is the last line of: compare_type_rank (gfc_symbol *s1, gfc_symbol *s2) { int r1, r2; r1 = (s1->as != NULL) ? s1->as->rank : 0; r2 = (s2->as != NULL) ? s2->as->rank : 0; The call is: if (f2 != NULL && compare_type_rank (f1->sym, f2->sym)) Seemingly f2->sym is NULL. -- burnus at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |janus at gcc dot gnu dot org Status|UNCONFIRMED |NEW Ever Confirmed|0 |1 Known to fail| |4.5.0 Last reconfirmed|0000-00-00 00:00:00 |2009-07-24 18:41:19 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40848
