Dunno if I may call myself an expert, but something that would really help in diagnosing the problem, is to try to reduce the code to a small code snippet that produces the problem. It is hard to comment without seeing any actual code. The simple fact that code seems to work correctly on one system (FreeBSD) doesn't mean it is necessarily correct, as I discovered myself more than once :(. Did you try the gcc newsgroups?
