• Ensure that the header 'DebugAllocator' and its description accurately reflect the intended usage and behavior of the allocator, especially since the previous section was 'GeneralPurposeAllocator'. If this change is intentional, confirm that all associated references and details have been updated consistently.

## `DebugAllocator`

course/advanced/memory_manage.md:138

• Verify that the reference to 'DebugAllocator' is intended to replace all instances of 'GeneralPurposeAllocator' throughout the document. This ensures the naming and documentation are consistent with the new allocator implementation.
