Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Pass marked buffer offsets safe without recursing through transparent wrappers, allowing negative summands to hide and cause OOB access.
Buffer Overflow: Bitmask width was log2(size) instead of actual size, permitting overlapping subslices and buffer overflow.
Memory Corruption: Deleting derived class through base pointer without virtual destructor is undefined behavior.
