The difference is that the "complete object constructor" also constructs the virtual base classes. I have no idea why g++ generates both for classes with no virtual base classes. And if there is some reason for that, then I have no idea why, when the functions are identical, it doesn't simply use two symbol names for two instances of the function. This is gcc PR 3187 (http://gcc.gnu.org/PR3187). I see that that PR has been suspended, although I don't agree with the cited reason; we don't need to do any ABI work to emit two symbols for one copy of the constructor. Ian
