@nico @gribozavr is correct that this is because of `vector<const T>`. I think I'd consider this a bug for now, but IMO we should just remove the `allocator<const T>` extension that allows this. It has bitten at least me way too often when working on `vector`, and isn't supported by any other major vendor: https://godbolt.org/z/8MPaP94cz. @ldionne Any thoughts on this?
