C++20 defines
std::byte*
to have the same aliasing properties aschar*
. Hence, we mark it with the__may_alias__
attribute under gccand clang.
Fixes #663
(Actually couldn't find whether this requirement is already in C++17 or not but gcc and clang already implement this in the compiler, trusting Niall on this part)
