>Description:
g++ accepts the following code without generating a warning or an error, though it should warn about trying to access the private member "foo" of class A:
/* snip */
class A {
static int foo;
};
int A::foo = 42;
class B : public A {
public:
int MyFoo(void)
{
return foo;
}
};
int main(int argc,char **argv)
{
class B b;
return b.MyFoo();
}
>How-To-Repeat:
Save the above program as "foo.cpp", then compile as follows:
$ g++ -Wall foo.cpp
g++ will compile the program without generating an error or a warning, even though A::foo is private within B::MyFoo. g++ will warn if the initializer for A::foo is moved out of sight.

Confirmed. However, already fixed in 3.4:
g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c x.cc
x.cc: In member function `int B::MyFoo()':
x.cc:4: error: `int A::foo' is private
x.cc:10: error: within this context
