Clang does not properly resolve classname::classname as constructor

Extended Description

Given the following:

struct A {
A() {}
A(int) {}
};

int main() {
int i;
{
A::A(i); // <---
}
}

Clang parses the marked line as a variable declaration:

ConsoleApplication1.cpp:9:13: warning: declaration shadows a local variable [-Wshadow]
A::A(i); // <---
^

This is due to clang parsing A::A as a reference to the injected class name instead of as an illegal reference to A's constructor.
