I’ve fixed undefined behavior in large C++ code based caused by misaligned reinterpret casts - the solution is to use memcpy

  It's such a good idea that they made a special cast that does just that in C++20: https://en.cppreference.com/w/cpp/numeric/bit_cast https://en.cppreference.com/w/cpp/numeric/bit_cast

  And in most cases (at least in optimized builds) the memcpy will be optimized out.
