Detailed Description

template<std::size_t Sz>
struct misalign_array< Sz >

Create an array that is guaranteed to be mis-aligned.

Now ASAN reports mis-aligned accesses, [1], which could occur using MOV instructions [2] as in 64-bit mode alignment checking of ring 3 can be enabled. But on Intel & AMD mis-aligned access to memory-operands is not an issue in ring 3, so ubsan is conservative (obeying the Standard).
