Hi Thorsten, [snip]
able to copy e.g. ptr_vector<Base> is a key property of the library, and there is no way that is going to be removed from the library.
You can accept that or not. If you don't, we have nothing more to discuss. If you do, I would be happy to work with you and others to make the library even more useful, including finding someway of supporting that all memory is allocated from the same underlying allocator.
I have no problem with the library in general. I simply found it impossible to make a clone when using it. I've made my suggestion of passing the parent allocator to the clone_allocators static clone method. I'm happy to leave it at that. At the end of the day, I just change my local branch anyway ;) I'll think about a way of doing it that you may find preferable over passing the allocator to the clone_allocator. Regards, Christian
