It said something about contacting this address. What should I do to
register an account?

Hello,

I have a bug to submit for GCC but the account creation is disabled. Any ideas?

Best regards,

I would like to report a bug in GCC, but I am unable to create an
account with the bug tracker. The bug I would like to report is as
described below.


Brian



SUMMARY:

Unable to define a static template member function of a nested class
as a friend of a sibling class.



EXAMPLE:

template <typename T> class A {
 public:
  class B;
  template <typename U> class C;
};

template <typename T>
class A<T>::B {
 public:
  template <typename U> static void Create();
};

template <typename T> template <typename U>
class A<T>::C {
 C() = default;
 friend void B::Create<U>();
};

template <typename T> template <typename U>
void A<T>::B::Create() {
  C<U>{};
}

int main() {
  A<int>::B::Create<char>();
}



COMPILATION COMMAND:

gcc -std=c++ -Wall -Wextra -fno-strict-aliasing -fwrapv
-fno-aggressive-loop-optimizations test.cpp -o test



DATA COLLECTION COMMAND:

gcc -v -save-temps -std=c++11 -Wall -Wextra -fno-strict-aliasing
-fwrapv -fno-aggressive-loop-optimizations test.cpp
