4.0 Regression] use of `enumeral_type' in template type unification (original) (raw)

Source: ------- #include #include using namespace std; ////////////////////////////////////////////////////////////////////// enum E { E0, E1 }; ////////////////////////////////////////////////////////////////////// template class A; template ostream& operator << (ostream& out, A a); template class A { friend ostream& operator << (ostream& out, A a); int mI; public: A(int i) { mI = i; } }; template ostream& operator << (ostream& out, A a) { out << a.mI; return out; } ////////////////////////////////////////////////////////////////////// int main() { A a = 5; cout << a << endl; A b = 4; cout << b << endl; system("Pause"); return 0; } Comment 1 Kriang Lerdsuwanakij 2004-09-06 14:27:22 UTC Confirmed. It has failed since GCC 3.0 - a regression to GCC 2.95.x. Comment 2 Giovanni Bajo 2004-09-06 14:41:45 UTC A reduced testcase is needed to analyze the bug, because it definetely has to do with some other operator<< for ostreams defined in the standard headers. Can anybody help? Comment 3 Kriang Lerdsuwanakij 2004-09-06 17:16:16 UTC A simple testcase: enum E { E0, E1 }; template <class T,class U> class A {}; template void f(A<E,T>) {} template void f(A<int,E>); Comment 4 Mark Mitchell 2004-09-09 04:30:08 UTC Mine. Comment 7 Mark Mitchell 2004-09-14 00:44:30 UTC Fixed in GCC 3.4.3. | | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | |
