For later builds it was just gone again. Not sure if anyone wants to figure out what was special about the two SVN revisions.

Unlikely that stuff from November would do it oh so suddenly. Unlikely, but possible. r274569 modified the termination conditions for the equiv_node() recursion that dim@ posted, so it's definitely relevant. > > It’s hard to exactly narrow it down as there was a lot of other breakage in the tree but I know that r276729 finished a full universe and I hadn’t noticed the problem before. So I would almost assume it was something after that (but obviously it could be a combination of things). > > /bz > > — > Bjoern A.
