<div>
<pre>template <int A> int a() { return 1; }
class B {
static constexpr int b() { return 2; }
int a1() { return a<B::b()>(); }
int a2() { return a<this->b()>(); }
};
The above compiles in gcc but clang fails with the following error:
note: candidate template ignored: invalid explicitly-specified argument for
template parameter 'A'
The problem is in B::a2(). Clang doesn't like this->b() being used for template
parameter A. clang has no problem with using B::b() as seen in B::a1().</pre>
