Detailed Description

Manages dynamic memory allocation.

This structure manages the heap, including free lists for memory blocks, garbage collection, and allocation strategies.

Fields:

heap_start – Base of the user heap region
heap_end – Current end of the heap
metadata_size – Bytes reserved for bins and arenas
stack_top – Upper bound of application stack
stack_bottom – Lower bound of application stack
last_allocated – Last block returned (NEXT_FIT)
num_size_classes – Total size classes available
num_arenas – Number of arena partitions
arenas – Array of arena metadata
mmap_list – Linked list of mmap’d regions
free_lists – Segregated free lists by size class
gc_thread – Garbage collector controller
