[Bug c++/31525] New: b was not declared in this scope in inherited template class

2007-04-10 Thread edufer at gmail dot com 
Fails on 4.1.2 and 3.4.2. Works on 3.2.2

When compiling the following code:

template  class A {
protected:
int b;
};

template  class B :  public A<_T> {
public:
void test_ok() {
this->b = 17;
}

void test_fail() {
b = 17;
}
};

The method test_ok compiles OK but the test_fails gets the following error:

bug-gcc.cpp: In member function void B<_T>::test_fail():
bug-gcc.cpp:18: error: b was not declared in this scope

The full command line is:

Many thanks for your help.
