[Bug c++/41038] New: Parsing error related to qualified name id

[davidxl at gcc dot gnu dot org]

The following code compiles ok with -DOK1 or -DOK2. The default case generate
the following error which seems wrong.

gmo2.cc: In member function 'int Packer<T>::foo()':
gmo2.cc:17:29: error: request for member 'size' in 'Packer::var', which is of
non-class type 'const std::string&'



#include <string>
template <typename T>
struct base {
 const std::string& var;
};

template<typename T>
struct Packer 
 : public base<T> 
 {
 int foo() {
#ifdef OK1
      return  Packer<T>::size;
#elif defined (OK2)
     return base<T>::var.size();
#else
     return  Packer<T>::var.size();
#endif
 }
 const std::string& var;
 const int& size;
};

It looks like the compiler is not properly handling injected class names.  The
original example was not the best use of the injected class name, but should be
accepted.  Jonathan's example is better code, and still shows the problem.

The workaround is to drop the qualifier.  Since the base is public, its member
will be found.
