Hi Paul,
The problem may well be where Joe pointed it out.
In
if (expr1->ts.type == BT_CHARACTER && expr1->ts.u.cl->length)
{
if (!expr1->ts.u.cl->backend_decl)
{
gfc_se tse;
gfc_init_se (&tse, NULL);
gfc_conv_expr (&tse, expr1->ts.u.cl->length);
expr1->ts.u.cl->backend_decl = tse.expr;
}
type = gfc_get_character_type_len (gfc_default_character_kind,
expr1->ts.u.cl->backend_decl);
}
the fact that expr1 has a substring reference is not taken into account,
so it might be necessary to calculate the length of the string
from expr1->ref->u.ss.end - expr1->ref.u.ss.start + 1. You may have
to take care not to calculate any functions twice, though.
Hope this helps a little bit.
