------- Comment #4 from dberlin at gcc dot gnu dot org 2006-01-24 03:15 -------
These ICE's are very hard to fix without real loop distribution. They
basically all concern the perfect nest transformation.
I'm not even sure it's worth attempting to fix them by hacking up the perfect
nest transformation further.
