I'm curious what the 3.3 numbers are, but the same proprocessed file may not compile there since the parser changed in 3.4. Not critical. The regression in 4.0 is pretty bad, definitely file a PR. See: http://gcc.gnu.org/bugs.html for instructions. It may be a known problem or a new one, let's find out. If you can't reduce the .ii testcase, don't worry so much. Just bzip it and submit it as a compressed attachment. --Kaveh -- Kaveh R. Ghazi [EMAIL PROTECTED]
