Allocators of anonymous access types are almost never what you want. This is 
so true, in fact, that we have proposed a Restriction for this 
"No_Anonymous_Allocators", which I recommend is part of every program. (Of 
course, that will have to wait until compilers implement it; it wasn't 
formally proposed until 3 weeks ago, but it was accepted at the Brest 
meeting and thus will appear in the next working draft).

The next version of Janus/Ada will print out a warning for any anonymous 
allocator (the restriction would turn it into an error, of course).

                                     Randy.
