Hi Andrew thanks, it seems like we have some code which looks like this

alignas(64) std::uint8_t foo[1024];
const auto* int_ptr = reinterpret_cast<const std::int32_t*>(foo);

// later dereference int_ptr

as far as we understand it this is a strict aliasing violation, meaning we will
adapt the code, thanks for a hint in the right direction
