These reinterpret_casts can't possibly be constexpr.
Simple test case:
#include
constexpr b
Tested on Linux-x64.
The tests apparently would never fail unless the arrays are global
and the pointer arithmetic local. However, these tests should
ensure that the results are the same regardless of optimizations,
and these test fail with the current compiler unless the specializations
are prese
