Pete Goodeve, I have a perhaps naive suggestion. Have you tried deleting your generated/objects/ directory (or perhaps generated.gcc4/objects/ if you are doing a hybrid build) and rebuilding? It is possible that you simply have a stale object file causing a problem and that is why you are not seeing the problem in the source file. I will try building a gcc2/4 hybrid build tonight and see if I can reproduce the problem. John Scipione
