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]
