I can reproduce the failure with
gcc-Version 4.6.2 20111011 (prerelease) [gcc-4_6-branch revision 179784]
(GCC)
4.6.4 20120310 (prerelease) [gcc-4_6-branch revision 185168] (GCC)
however, for some reasons not with
gcc version 4.6.2 20111212 [gcc-4_6-branch revision 182222] (SUSE Linux)
However, also with 4.8.0 20120320, I do see a failure in valgrind:
==6587== Invalid read of size 4
==6587== at 0x5859C5: resolve_symbol(gfc_symbol*) (resolve.c:10613)
==6587== by 0x5A3253: do_traverse_symtree(gfc_symtree*, void
(*)(gfc_symtree*), void (*)(gfc_symbol*)) (symbol.c:3386)
==6587== by 0x58FC13: resolve_types(gfc_namespace*) (resolve.c:13961)
==6587== by 0x58FCF7: resolve_types(gfc_namespace*) (resolve.c:13972)
==6587== by 0x584043: gfc_resolve(gfc_namespace*) (resolve.c:14061)

In 4.6, I have sym->formal_ns == NULL, which crashes for
"sym->formal_ns->refs++;". In case of 4.8, it is more difficult as there is no
crash for me but just the valgrind warning.
