I'm not sure about that. It might be a bit speculative, but I think I remember problems with that unless I rebuilt everything with new GCC (this was not with 4.5 and 4.6, but some older versions). > On the other hand without any specifics as to what failed for you it is > difficult to judge whether you found an ABI break or simply a bug in > your library or code... If rebuilding with new GCC fixes the problem I think it means the problem was with ABI.
