Summary: no matching constructor for initialization errors not
detected in g++
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
Currently g++ doesn't warn or error on invalid code such as...
template <class T> class Array1D {
Array1D(int n, T *a);
};
template<typename T>
struct A {
Array1D<int> x;
A() : x(1, (const int*)0) {}
};
for which clang++ produces the error...
