<pre>C++ [expr.const]p2:
"A conditional-expression e is a core constant expression unless the evaluation
of e, following the rules of the abstract machine (1.9), would evaluate one of
the following expressions:
(2.1)
— this (5.1.2), except in a constexpr function or a constexpr constructor that
is being evaluated as part of e;"
So while "B::b()" is a constant expression, "this->b()" is not; clang is
correct to reject this.</pre>
