The following simple patch

Index: parse.c

              gfc_free_st_label (gfc_statement_label);

+#endif
              return ST_NONE;
            }
        }

get rids of the ICE, but I don't understand why we have an ICE in first place.
The patch simply retains the labeled empty statement in the list of labels.
I haven't tested the patch beyond a simple program similar to those posted
by Bernhard.
