Bug #: 53403
Summary: Function template friend denied access to private
types of granting template class.
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: ibugs@qult.net
The following code compiles with GCC 4.4 but not since 4.5, until at least
4.7.0.
template <typename T>
class Foo {
typedef void type;
template <typename U> friend void f();
public:
Foo() {}
};
template class Foo<void>;
template <typename T>
void f()
{
typedef Foo<void>::type type;
}
int main()
{
f<void>();
}
If the function template is declared before the definition of the class
template, or if the Foo<void> class is instantiated after f's definition, the
code compiles. The error appears only with private types, not other private
members.
Easy to work around, but still... :/

The problem also exists for gcc 4.8.0 20120513 (experimental) with or without
activating C++11 support. Further, if the reference to the type in template f
is a dependent form, like
typedef typename Foo<T>::type type;
the error does not occur. This looks like a compiler-defect to me.

Confirmed, this possibly got broken when Jason implemented the C++11 friend
rules

Works in mainline. I'm adding the testcase and closing the PR.
