1 high-severity fix in this history; regressions here are high-impact.
Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Incorrect pointer math during hash table compaction in `_md_shrink` allowed heap corruption or segmentation faults. Future modifications to the table compaction or resizing algorithms must ensure pointer arithmetic limits are strictly verified.
Denial of Service: Reference leaks in the `md_pop_one` identity return path and pointer logic failures in `md_clear` caused cumulative memory leaks during dictionary modifications, exposing applications to memory exhaustion.
Denial of Service: Transient keyword dictionaries allocated in `IStr_New` were leaked during case-insensitive string instantiation, creating a denial of service risk under sustained header-parsing workloads.
