dynamic memory allocation

Reserving memory moment to moment, as needed, without having to reserve a fixed amount ahead of time. Modern operating systems perform dynamic memory allocation for their own use. They may also perform the same operation for their applications, or they may include programming interface functions (APIs) that allow the applications to allocate and de-allocate memory as needed. See garbage collection.

In fact, we believe that (at least in the intraprocedural case) precise flow-insensitive may-alias analysis becomes polynomial even with arbitrary levels of pointer indirection (maintaining the restriction that there is no dynamic memory allocation) if the number of levels of dereferencing (i.e., the maximum number of staxs in an expression) is restricted to some fixed k.
The constraint of static memory allocation is a fundamental flaw because the most general kind of computational process (a Turing Machine process) requires dynamic memory allocation. This requirement distinguishes the Turing Machine from the Finite-Automaton in the theory of computation; the latter is characterized by static memory allocation.
The suggested improvements to this program emphasize the use of dynamic memory allocation and the replacement of external variables with automatic variables.
