--- Comment #1 from Robert Dubner <rdubner at gcc dot gnu.org> ---
Jim, this one is yours.  parser_compute is being called twice, from
compute_cond: in parse.y.  (Approximately line 6300; its the second appearance
of parser_compute in parse.y.)

The second time, the current.compute_label() value is NULL.
