Bug ID: 30586
Summary: Clang-cl Friend class error: elaborated type refers to
a type alias
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangb...@nondot.org

Reproduction
While trying to get an MSVC code base compiling with clang-cl, we ran against
following error: elaborated type refers to a type alias
Code (For full code, see attachment):
template<typename T>
struct A {};
template<typename T>
struct B
{
using A = A<T>;
friend class A;
};
int main(int argc, char **argv)
{
B<int> b;
return 0;
}
However, the same code does compile with MSVC2013.
Known workarounds:
- drop the class-keyword
- Use fully qualified name (A<T>) with friend declaration before the
using-statement
