> @BillyONeal do you know if 19.11 has the aligned_storage issue on x86?

aligned_storage is still capped at what the library can fake with unions. It 
would be an ABI break to change it to use alignas, so things where the x86 
stack temporarily breaks T's usual alignment rules will affect it (and for all 
releases using VS2015's ABI). We recommend customers use `alignas(T) unsigned 
char space[sizeof(T)]` if they can't tolerate such limitations.
