Compiler Error C2752
'template' : more than one partial specialization matches the template argument list
An instantiation was ambiguous.
The following sample generates C2752:
// C2752.cpp
template<class T, class U>
struct A {};
template<class T, class U>
struct A<T*, U> {};
template<class T, class U>
struct A<T,U*> {};
// try the following line instead
// template<class T, class U> struct A<T*,U*> {};
int main() {
A<char*,int*> a; // C2752 an instantiation
// OK
A<char*,int> a1;
A<char,int*> a2;
A<char,int> a3;
}
