<pre>The following program compiles successfully on GCC and MSVC:
template<typename X, typename... Y>
void f(X&&, Y&&...)
{
}
template<typename X>
void f(X&&, const double&)
{
}
int main()
{
void(*fptr)(const int&, const double&) = &f;
}
Using Clang (<a href="https://godbolt.org/z/5jE18P">https://godbolt.org/z/5jE18P</a>) we get:
<source>:13:46: error: address of overloaded function 'f' is ambiguous
void(*fptr)(const int&, const double&) = &f;
^
This seems to affect all Clang versions. Tested on trunk, 11.0.0 and 3.0.0.</pre>
