template subclass bug

[Jon Wilkening]

dear g++ developers,

I have found the following bug when compiling under cygwin (g++ version 
3.4.4 on a pentium 4 laptop) and under solaris (g++ version 3.4.3 on an 
sunblade 2000).  It works correctly in fedora core 2 on a pentium 4 
laptop when compiled with g++ version 3.3.3, and on the sunblade 2000 when 
compiled with Sun's native CC compiler.

Best regards,
Jon Wilkening

-----

the file subclass.cpp is included below.  It should compile without 
errors, but instead gives:

math1 ~ 81% g++ subclass.cpp
subclass.cpp: In member function `void B<T>::out()':
subclass.cpp:17: error: `x' undeclared (first use this function)
subclass.cpp:17: error: (Each undeclared identifier is reported only once 
for each function it appears in.)


if I comment out line 17 and uncomment line 18, it works as expected, but 
it shouldn't be necessary to qualify x with the superclass name.

------

#include <iostream>
#include <stdio.h>
using namespace std;

template<class T>
class A {
public:
    T x;
    A(T x_) : x(x_) { }
};


template<class T>
class B : public A<T> {
public:
    B(T x_) : A<T>(x_) { }
    void out() { cout << x << endl; }
    // void out() { cout << A<T>::x << endl; }
};


int main() {
    B<int>    i(5);
    B<double> w(5.3);
    i.out();
    w.out();
}
