--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
In the originally submitted test program, both GCC 7 and EDG eccp 4.11 accept
all cases but #5. Clang 3.8 also rejects #5 and #7. Below is a reduced test
case that reproduces the same behavior. By my reading, case #5 is invalid but
case #7 is valid because the friend function bar is found by argument dependent
lookup. The invalid case wasn't handled correctly until r219689 committed to
resolve bug 59366. Closing as duplicate of that bug.
So I'm inclined to resolve this bug as fixed.
$ cat t.C && gcc -S -Wall -Wextra t.C
struct Foo { };
struct Bar
{
template <class T>
friend void bar (const T&, int);
};
int main ()
{
Foo f;
bar (1, 5);
bar (f, 7);
}
t.C: In function ‘int main()’:
t.C:13:3: error: ‘bar’ was not declared in this scope
bar (1, 5);
