           Summary: Invalid error message 'has no member named' when
                    referring directly to the base class
           Product: gcc
           Version: 4.5.1
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ethouris@gmail.com

Short C++ code that reproduces the problem.

There is one case, having that:

struct Base { };
struct Concrete: Base { void setValue( string, string ); };

and using:

v->BaseType::setValue( this->name, this->value );

[with template parameter BaseType = Base]

generates the following error:

newmpl.cc:37:35: error: âstruct Concreteâ has no member named âsetValueâ

which is a lie, because Concrete::setValue exists. The mistaken here is the
name of the class that does not have given member, which should be âstruct
Baseâ here, because this call refers directly to the given class (not to the
'v' pointer's class).

Please find the reproduction example in attachment (no dependencies but C++
standard library). You can see that the 'Base' class has 'setValue' commented
out in order to make this error occur.

The same behavior is with the latest version, gcc 4.7.0.
