Please provide preprocessed source and the g++ options used to compile it. If there's a way to obtain that from koji, I don't know what it is. I don't have other access to a machine with gcc 4.5 at the moment, so it's rather difficult for me to get the preprocessed source. This can be reproduced by building the openvrml package on the F14 or development branches. Just build it with mock... Created attachment 443222 [details]

Dodji, this error starts appearing with r156316 (i.e. your PR42713 + PR42820 patch). Can you please look at it? -O0 is enough to reproduce (with # lines stripped -O0 -std=gnu++0x). Hopefully correctly simplified testcase, at least I get the same error on it with r156316 and no error with r156312.
