Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Memory Corruption: Integer overflows during buffer reallocation can lead to heap-based buffer corruption when processing large inputs, causing process instability or arbitrary code execution. This is a recurring issue addressed in both historical commits and public advisories.
Double Free: Improper handling of statically allocated buffers during error states or cleanup routines can result in double-free or invalid-free conditions, compromising memory integrity during parser teardown.
Memory Corruption: Parsing malformed Unicode surrogate pairs or invalid JSON input can cause out-of-bounds reads or crashes due to insufficient boundary checks before advancing memory pointers.
