[Bug c++/26102] New: [4.2.0 regression] "using Base::member" nonsense

[jan at etpmod dot phys dot tue dot nl]

Consider the following reduced testcase:

template <class T> struct B1 { int i(); };

struct B2 { int i(); };

template <class T> struct C : public B1<T>, public B2
{
        using B2::i;
        void f()
        {
                i();    // fails, should be accepted
                i.i();  // accepted, should fail
        }
};

With today's trunk this gives:

t.cpp: In member function &#8216;void C<T>::f()&#8217;:
t.cpp:10: error: no match for call to &#8216;(B2) ()&#8217;

"i" seems to be resolved as the base class B2, 
as opposed to its member "i()"

Worked on 20051217 but fails on 20060127.
Fails also in "4.1.0 20060130"

------- Comment #2 from mmitchel at gcc dot gnu dot org  2006-02-14 09:13 -------
One could argue that this should be P1, but I'm going to make it P1, since the
valid code that is incorrectly rejected is somewhat obscure.

This issue will not be resolved in GCC 4.1.0; retargeted at GCC 4.1.1.

Will not be fixed in 4.1.1; adjust target milestone to 4.1.2.

Janis,
  Could you do a regression hunt on this bug?
Thanks,
