Wrong function override resolution for const arguments

class Foo {};
void foo(int v) {}
void foo(const char *v) {}
void foo(const Foo &v) {}
void foo(char v) {}


void test()
{
    foo(5);
    foo("hoo");
    foo('a');
    char *var = "var";
    foo(var); // Jumps to last override, regardless of its type
    Foo f;
    foo(f); // Jumps to last override
}
