--- Comment #6 from Tom de Geus <tom at geus dot me> ---
I can confirm that this bug is still there, e.g. on the standard gcc on the
latest Ubuntu. Clang and MSVS are compiling fine.
Here is my failing (similar) problem:
```cpp
#include <iostream>
#include <vector>
template <class T>
auto foo(const T* A)
{
return A[0];
}
template <class T>
struct impl
{
template <typename F>
static auto bar(const T& A, F func)
{
return func(&A[0]);
}
};
int main()
{
std::vector<size_t> A = {20, 3, 4};
std::cout << impl<decltype(A)>::bar(A, &foo<size_t>) << std::endl;
return 0;
}
```
