I have run into this bug or a similar bug while porting my code from MSVC to
GCC. I need to declare that a class in the global namespace is a friend of my
template class. However, I discovered that the bug still occurs if no templates
are involved. Here's my repro:
class Friend;
namespace Foo
{
class Base {
};
class Derived : protected Base {
friend class Friend;
};
}
class Friend {
void F(const Foo::Derived* data) const
{
// error: 'Foo::Base' is an inaccessible base of 'Foo::Derived'
const Foo::Base* dataB = data;
}
};
The problem disappears if either (A) Derived is not in a namespace, or (B)
Friend is in a namespace (the forward declaration of Friend is required and, of
course, must be put in the namespace too).
