That has uncovered a slew of errors not caught with gcc 4.4.5 or clang 3.3. Note that the clang trunk bug I reported has been fixed so it will be interesting to see if clang picks up the same (or other errors). I need to convert to a debug build so I can get through all the errors--will attach a list when complete. Best regards, -Tom -------------- next part -------------- An HTML attachment was scrubbed...

They look like legit problems but I haven't tried to fix them. Best, -Tom -------------- next part -------------- An HTML attachment was scrubbed...
