Sorry, you are right. If -O2 works it can't be the lib.

Try to make the failing file as small as possible (but still
failing). Save the preprocessed file and again reduce it as much as
possible. That should give you a minimal testcase for the bug. 

Save the tempfiles for that source and report the input and tempfiles
as bug against g++-3.4.

PS: you might want to try g++ 4.0 too to see if the bug is still there.
