[Bug c++/34667] New: Ambiguous error message on partial member specialization

["philippe at fornux dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The following code will not compile even if the error message doesn't make
sense, because it obviously knows which member to instantiate.

This may be a compiler bug issue, or and ambiguous error message.


#include <iostream>


using namespace std;


template <typename T>
    class vector
    {
        vector();

    public:
        template <unsigned S>
            vector(T (& array) [S])
            {
                cout << sizeof(array) / sizeof(T) << endl;
            }
    };

int main()
{
    vector<int> a((int []) {0, 1, 2, 4, 5});
}



$ g++ temp.cpp
temp.cpp: In function `int main()':
temp.cpp:22: error: no matching function for call to
`vector<int>::vector(int[5])'
temp.cpp:9: note: candidates are: vector<int>::vector(const vector<int>&)
temp.cpp:15: note:                 vector<T>::vector(T (&)[S]) [with unsigned
int S = 5u, T = int]
temp.cpp:10: note:                 vector<T>::vector() [with T = int]
