I was getting these failures before my patch that added eustores, and kenny was responsible for regtesting the tree for the ipa-* patches :) (I always bootstrap and regtest with fortran on). > PS: PR 22619 appeared somewhere between 20050716 and 20050717, so > patches that could possible have messed up are: The culprit in this case is indirectly the patch that added ipa-reference AFAICT. -fno-ipa-reference seems to fix the bug on my computer, see if it helps you too. No clue why. Given that it happens after CSE, I imagine it's enabling CSE to eliminate something it didn't expect to be able to eliminate.
