I think it is. It comes from:

2002-03-21  DJ Delorie  <dj@redhat.com>

	* bb-reorder.c (make_reorder_chain_1): Protect against
	when redundant edges are omitted.
	* predict.c (dump_prediction): Likewise.

I've submitted the backport patch for approval on the 3.2 branch.

P.S: does the testcase come from Allegro?
