[Bug c++/34920] New: Members in nameless union

[extronus at gmail dot com]

Members in nameless union defined in template base class cannot be accessed by
template derived class. Methods in base class can access members.

Tried on 3.4.5 (mingw) and 4.1.2 (gentoo)

Simplified code :

template 
class base
{
  public :
typedef TYPE arrayType1[4];
typedef TYPE arrayType2[2][2]; 
union {
  arrayType1 o; ///< One dimensional array
  arrayType2 t; ///< Two dimensional array

  struct
  {
TYPE m11; TYPE m12; TYPE m13; TYPE m14;
  };
};

void base_funk()
{
  o[0] = 0;
}
};

template 
class derived : public base
{
  public :
void der_funk(TYPE v) {o[0] = v;}
};

more simplified

-
template 
struct base
{
  float a;
};

template 
class derv : public base
{
  void der_funk()
  {
a = 0;
  }
};


while this one works
--
template 
struct base
{
  float a;
};

template 
class derv : public base
{

  void der_funk()
  {
a = 0;
  }
};
