- -- Allocation strategy:
-
- -- Pool is a regular stack array, no use of malloc
- -- user specified size
- -- Space of pool is globally reclaimed by normal stack management
-
- -- Used in the compiler for access types with 'STORAGE_SIZE rep. clause
- -- Only used for allocating objects of the same type.
