Detailed Description

Utilities for intentionally "leaking" memory at program exit.

When a program exits, the OS reclaims all process memory anyway. Running destructors that only free memory is wasted work that slows down shutdown. This is especially noticeable for large caches like library symbol/footprint data structures with deep object hierarchies.

When built with address sanitizer (KICAD_SANITIZE_ADDRESS), these utilities use __lsan_ignore_object() to mark the memory as intentionally leaked, preventing false positive leak reports.
