Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Memory Corruption: Panic-safety bug in String::retain could leave the string in an invalid UTF-8 state, leading to memory corruption; the fix uses a SetLenOnDrop guard to restore length on panic.
Memory Corruption: Integer overflow in round_up_to during alignment rounding could produce an undersized allocation, leading to out-of-bounds memory access; the fix adds overflow checks.
