--- Comment #1 from Marc Glisse <glisse at gcc dot gnu.org> ---
The optimizer has trouble seeing through the dynamic initialization of vtable.
Interestingly, compiling with -std=gnu++17 lets the optimizers do their job
(constexpr lambda conversion to a pointer?). But it still points at a missing
optimization.
