[Bug c++/17071] New: bogus error taking the address of an overloaded function

[sebor at roguewave dot com]

Gcc 3.4.0 gives an error on the following well-formed test case. In
the call to bar in main the reference to foo should match the ordinary
overload because argument deduction for the template foo fails (13.4,
p2) and thus there's only one function in the overload set.

$ cat t.cpp && g++ --version && g++ -c t.cpp
int foo (int);
template <class T> T foo (T, T);

template <class T, class U> int bar (T, U);

int main ()
{
    bar (0, &foo);
}
