Hi,
here is a shortened version of the code-snippet in question:
template<int SIZE>
class B
{
public:
class P {};
};
template<int SIZE>
void the_bug(B<SIZE>::P p)
{}
void test()
{
// the_bug<10>(B<10>::P()); // line X, compiles
the_bug(B<10>::P()); // line Y
}
It comes down to the question, whether the compiler should be able to
deduce the template-argument SIZE of the_bug from a function-argument,
in which SIZE is a template-argument of an *enclosing* class.
(Note, that if one explicitly calls the_bug<10>, as in line X, the code
compiles fine. )
After browsing through Section 18.4.2 of the C++-Standard, I believe
that compilers do not need to be able to perform this deduction, so the
described problem is probably not a bug in gcc.
Best regards,
Joerg Peters
