It appears clang has a bug that was once in gcc but has been fixed,
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51184.

clang compiles the following invalid code (taken from the gcc bug report),
which it shouldn't.


///////////////////////
template<typename T>
struct S{};

struct A
{
  virtual void f() = 0;
};

int main()
{
  S<A(int)> s;
}
