Fix unaligned map_handle::zero_memory on windows and support COW #133

Closed patstew closed 3 months ago

patstew commented 5 months ago

If you try to zero an unaligned address in a map_handle, it zeros the whole surrounding page on windows. Also pass the COW flag on to the map handle, otherwise the section is COW but the map is unwritable.

Thanks for the fix!
