The deadlock is a bigger concern I think. > Interestingly, the problem looks like a compiler one.

Anyway, the coding style requires to save the return value in a variable, instead of nesting the call in an "if" condition. And the "if" check should be explicitly != 0 because it is not a real boolean. PS: please do not top post and avoid HTML emails, thanks
