[Bug fortran/40629] Host association problem

[burnus at gcc dot gnu dot org]

------- Comment #2 from burnus at gcc dot gnu dot org  2009-07-03 10:13 -------
Confirmed. One first gets the error message from gfc_get_sym_tree (already been
host associated), followed by the segfault, which happens at
==12785== Use of uninitialised value of size 8
==12785==    at 0x500F17: gfc_resolve_expr (resolve.c:4459)
which is
  4457            /* Give the symbol a symtree in the right place!  */
  4458            gfc_get_sym_tree (sym->name, gfc_current_ns, &st, false);
  4459            st->n.sym = sym;

Thus one should add a check for "st == NULL" (e.g via gcc_assert) and fix
gfc_get_sym_tree.
