Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Integer overflows during input size calculations in multi-combinator macros can trigger panics, crashing parser threads and causing Denial of Service. This pattern has repeatedly appeared in multiple parser combinator macros.
Denial of Service: Sequence parser macros and parsing helpers like the `do_parse!` macro can suffer from integer overflow panics when computing combined token sizes from incomplete streams.
Memory Corruption: Unsafe handling of string allocations using `String::from_utf8_unchecked` can result in undefined behavior and memory corruption when processing malformed or malicious input byte sequences.
