When i try to compile this code there is an error but it's compiling fine with
"comeau online":
main.cc: In constructor `C<T>::C()':
main.cc:10: error: object missing in reference to `A::m_'
main.cc:25: error: from this location

But it's working fine with this->m_.p();  insteed of A::m_.p();

Following main.ii

# 1 "main.cc"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "main.cc"

struct X
{
  void p()
  { ; }

};

struct A{
   X m_;
};

template<typename T>
struct B : public A
{
   B():A(){Y=0;}
int Y;
};

template<typename T>
struct C : public B<T>
{
   C():B<T>()
   {
   A::m_.p();

   Z=0;
   }

T Z;
};


int main()
{
C<int> test;
return(1);
}

Hi, please note that for the same bahavior with the line, it's compiling:

((A*)(this))->m_.p();

Not a bug.

This has to do with two-stage name-lookup, see last bullet in
http://gcc.gnu.org/bugs.html#new34
and
http://gcc.gnu.org/gcc-3.4/changes.html

You could use
this->m_.p(), this->A::m_.p(), B<T>::A::m_.p()
