Below I provided an example demonstrating how placement new creates multiple objects within the same byte storage.

From C++ standard: Attempting to read or modify the stored value through any other type results in undefined behavior.

The first simple example: #include <bit> #include <cstdint> #include <iomanip> #include <iostream> std::uint32_t badBits(const float value) { // const prevents writes, but reading a float through a uint32_t pointer // still violates the strict-aliasi…
