I have to user-defined storage pools.
Is it OK to allocate ("new") by one of them and deallocate by the other
("Uncheked_Deallocation"), using conversions between access types.

No, as far as I know that's even erroneous. You must deallocated from the same
pool you allocated it.
If you think about it, it's quite obvious that you should take account of the
allocated item's
origin.

Are you sure, which item of Standard deprecates this?

This is not just a deprecation. See RM 13.11.2(16). It's erroneous, aka Nasal
Demons effect.

13.11.2(16). How could it be otherwise?

I meant the case when two pool variables share the same memory (e.g.
one pool uses other for allocation).
Well, I realize that eliminating this restriction would have bad impact
on memory debuggers.
