g++ doesn't seem able to match a template ctor of a template class where the ctor input is an internal class defined inside any template class.
I briefly skimmed the titles of the current regression issues and I didn't notice any that matched this, but I'm not 100% sure. I first posted this here thinking it was my code that was somehow wrong. http://www.gamedev.net/community/forums/topic.asp?topic_id=526736 demo.cpp ======================== template <typename T> class CFoo { public: class CZep {}; CFoo(int); // line 7. template <typename Z> CFoo(typename CFoo<Z>::CZep); // ## ctor I want ## ~CFoo(); CZep zep(); }; int main() { CFoo<int> x(1); CFoo<int>::CZep z; CFoo<int> w(z); // line 19: ## should call the ctor on line 8 ## return 0; } ======================== g++ demo.cpp ======================== demo.cpp: In function ‘int main()’: demo.cpp:19: error: no matching function for call to ‘CFoo<int>::CFoo(CFoo<int>::CZep&)’ demo.cpp:7: note: candidates are: CFoo<T>::CFoo(int) [with T = int] demo.cpp:3: note: CFoo<int>::CFoo(const CFoo<int>&) ======================== Specs: g++ [4.4.0] ubuntu [ibex, 64] This compiles fine on 3.3.2 and MSVC according to other testers at gamedev.net. Note: In the above example CZep is inside CFoo, but it doesn't matter if you put CZep inside class CBar<T> {} instead, just as long as it's inside another template class. Does the above code compile OK on other people's 4.4.0s? or is it a bug?
