The reason for that is in gfc_trans_call, around line 2316 (the call to
gfc_conv_missing_dummy): when we come here, we check both the list of actual
args and the list of formal args for optional args. This is need, because we
need the type of the formal arg. Problem is that apparently intrinsic
subroutines don't have a list of formal args when we come up here.
