 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?

 This patch "fixes" the problem, but I don't know if it's correct. 3.3
