--- Comment #5 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
The problem manifests itself in trans-array.c:
│6953 /* Set se = NULL in the calls to the interface mapping, to
suppress any
│
│6954 backend stuff. */
│
>│6955 for (; arg != NULL; arg = arg->next, formal = formal ?
formal->next : NULL)
│
│6956 {
│
│6957 if (!arg->expr)
│
│6958 continue;
│
│6959 if (formal->sym)
│
│6960 gfc_add_interface_mapping (&mapping, formal->sym, NULL,
arg->expr);
│
│6961 }
(gdb) call gfc_debug_expr(expr)
f[[(((/ 'xyz' /)))]]
(gdb) p formal
$21 = (gfc_formal_arglist *) 0x0
So, although we have an actual arglist, the formal arg list
has gotten lost somewhere, presumably because it is generic.
