Bug ID: 47587
Summary: Unexpected name lookup success in specialization of
tempalte class with variadic number of base classes
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++17
Assignee: unassignedclangb...@nondot.org
Reporter: anders.granlun...@gmail.com
CC: blitzrak...@gmail.com, erik.pilking...@gmail.com,

Consider the following c++ program:
#include <iostream>
class A
{
protected:
static constexpr int x = 123;
};
template<typename T>
using B = A;
template<typename ...T>
class C : B<T> ...
{
public:
static int f()
{
return x;
}
};
int main()
{
std::cout << C<>::f() << std::endl;
}
The name-lookup of x the method f should fail for the specialization C<> of the
template class C, but it does not when compiling with "-std=c++17
-pedantic-errors" (no compilation errros are outputed).
