[Bug c++/34893] New: Strangeness of name lookup in template function

["rvovsd at mail dot ru" <gcc-bugzilla at gcc dot gnu dot org>]

On compiling that code:

--- begin code ---
class Y {};

void f(Y*) { } // line 3. If comment - all ok

template < typename T>
void sel(T* a) { f(a); } //line 6

void f(void*) {}

int main(int argc, char **argv)
{
        sel((void*)0); //line 12
}
--- end code ---

Àppears error:
../main.cpp: In function ?void sel(T*) [with T = void]?:
../main.cpp:12:   instantiated from here
../main.cpp:6: error: invalid conversion from ?void*? to ?Y*?
../main.cpp:6: error:   initializing argument 1 of ?void f(Y*)?

If comment line 3, then work.
Also work, if line 3 move after line 6.

If functions f(Y*), f(void*) and sel(T*) placed in different header files, then
arise dependency on order including headers.
