Apparently destination pointer is null although it shouldn't be as this was checked upon it's creation: https://github.com/sagudev/ipc-channel/blob/4c01b78a108d761ac67407da1359b8293c7c93ef/src/platform/unix/mod.rs#L803

> Note that even if the effectively copied size (count * size_of::()) is 0, the pointers must be non-null and properly aligned.
