<div>
<pre>The code is as follow:
template <class T>
struct identity
{
typedef T type;
};
template <class T, typename T::type A>
struct foo {};
template <class T, T A>
struct foo<identity<T>, A> {};
int main()
{
foo<identity<int>,0> bar; // error here
}
clang++ accepts the code, but g++ rejects it with error messages. Initially, I
believe that this is a bug in g++, and reported the problem
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86193">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=86193</a>
However, the programmers of g++ believe that they are correct, and clang++
shall not accept the code. Would you please check this problem, and fix it if
it is really a bug in clang?</pre>
