------- Comment #2 from hjl at lucon dot org 2007-09-01 23:01 ------- In expand_iterator, there are
cleanup: gfc_free_expr (start); gfc_free_expr (end); gfc_free_expr (step); mpz_clear (trip); mpz_clear (frame.value); iter_stack = frame.prev; return t; } But frame.prev may be uninitialized when one of goto cleanup is called. This patch --- gcc/fortran/array.c.foo 2007-08-01 17:14:30.000000000 -0700 +++ gcc/fortran/array.c 2007-09-01 15:57:03.000000000 -0700 @@ -1281,6 +1281,7 @@ expand_iterator (gfc_constructor *c) mpz_init (trip); mpz_init (frame.value); + frame.prev = NULL; start = gfc_copy_expr (c->iterator->start); if (gfc_simplify_expr (start, 1) == FAILURE) seems to cure the ICE. Shouldn't gcc warn about this? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33276
