When Defect Report WG21-P2280R4 is implemented in MSVC, for libcxx's pathological tests for allocators with tiny
size_type
s likeuint8_t
, the compiler will notice that_Ints_max * _VBITS
undergoes integral promotion, but isn't smart enough to realize that we've avoided actual truncation.We should consistently follow our pattern of
static_cast
ing to avoid warnings with integral promotions.
