Should Allocation really implement Clone?

[danielkeller]

I'm pretty sure that the implementation of Clone for Allocation is unsafe, because you can clone it and call mapped_slice_mut on both, getting two &muts that alias.

[MarijnS95]

Oh yeah, that's entirely correct. There are more UB issues such as getting &mut access to possibly uninitialized memory, which is going to be fixed when I pick https://github.com/Traverse-Research/gpu-allocator/tree/uninit back up 😬
