a.cc:8:13: error: constexpr constructor never produces a constant expression

a.cc:8:13: note: non-literal type 'base' cannot be used in a constant
expression

I think clang is too strict here, I don't see where the standard requires all
base classes to have literal type for a constexpr constructor.
If derived::derived() is defined as defaulted the code is accepted, which is
inconsistent with the diagnostic because the base class is still non-literal.</pre>
