Memory Leaks with pointers

[Tricky]

Consider the following:
type a_t;
type a_t_ptr is access a_t;

type b_t;
type b_t_ptr is access b_t;

type a_t is array(integer range <>) of integer;
type b_t is array(integer range <>) of a_t_ptr;

begin

process
variable P : b_t_ptr;
begin

P := new b_t(1 to 10);

for i in 1 to 10 loop
p(i) = new a_t(1 to 10);
end loop;

DEALLOCATE(P);
wait;
end process;

have I just caused a memory leak by not deallocating all the elements
in the top level array? would you have to quit the simulator to free
it again, or just end the simulation?
