Each file contains realistic code that does something useful, but has ONE subtle bug. ## Your Task Fix the bug in each file so that: 1. The code compiles without warnings (`-Wall -Wextra -Werror`) 2. The code passes sanitizer checks (ASan/UBSan) 3. The code produces the correct expected output ## Files - `virtual_destructor.cpp` - Plugin system with memory management - `reference_to_temporary.cpp` - Configuration system - `iterator_invalidation.cpp` - Event queue processor - `unsigned_underflow.cpp` - Ring buffer implementation - `dangling_cstr.cpp` - Log formatting system - `init_order.cpp` - Coordinate system with units - `off_by_one.cpp` - Matrix border detection - `int_overflow.cpp` - Bulk price calculator Each file is independent. Fix bugs **IN PLACE** (modify the files in `input/`). PS: You are currently working in an automated system and cannot ask any question or have back and forth with an user. --- TASK END --- INFO 2025-12-16T01:08:08 +6894ms service=default version=1.0.155

in eight different C++ files. Since the user explicitly stated I am in an automated system and cannot ask questions, I must work autonomously and verify each fix with compilation, sanitizers, and expected output. This requires a systematic approach for each file: 1. **Read** the file to understand the code and identify the likely bug. 2. **Formulate a plan** for the fix. 3. **Apply the fix** using the `edit` tool. 4. **Verify** the fix by compiling and running the code with the necessary flags. I will use the `todowrite` tool to manage these eight independent tasks. The general C++ compilation and TDD workflow will be: * **Compile:** `g++ -std=c++17 -Wall -Wextra -Werror -o /app/input/a.out /app/input/` * **Sanitize/Run:** `g++ -fsanitize=address,undefined -fno-omit-frame-pointer -std=c++17 -Wall -Wextra -Werror -o /app/input/a.out /app/input/ && /app/input/a.out` I'll proceed file by file. ## Phase 1: Create Todo List I will create a todo list for each of the eight files. |  Todo 8 todos INFO 2025-12-16T01:08:21 +280ms service=bus type=message.updated publishing INFO 2025-12-16T01:08:21 +11ms service=bus type=session.status publishing INFO 2025-12-16T01:08:21 +3ms service=session.prompt step=1 sessionID=ses_4db4c9a39fferpdNSMYPj7kjeE loop INFO 2025-12-16T01:08:21 +56ms service=bus type=message.updated publishing INFO 2025-12-16T01:08:21 +22ms service=bus type=message.updated publishing INFO 2025-12-16T01:08:21 +12ms service=bus type=session.updated publishing INFO 2025-12-16T01:08:21 +13ms service=bus type=session.diff publishing INFO 2025-12-16T01:08:21 +64ms service=session.prompt sessionID=ses_4db4c9a39fferpdNSMYPj7kjeE exiting loop INFO 2025-12-16T01:08:21 +5ms service=session.compaction pruning INFO 2025-12-16T01:08:21 +64ms service=session.prompt sessionID=ses_4db4c9a39fferpdNSMYPj7kjeE cancel INFO 2025-12-16T01:08:21 +2ms service=bus type=session.status publishing INFO 2025-12-16T01:08:21 +4ms service=bus type=session.idle publishing INFO 2025-12-16T01:08:21 +37ms service=default directory=/app/input disposing instance INFO 2025-12-16T01:08:21 +6ms service=state key=/app/input waiting for state disposal to complete INFO 2025-12-16T01:08:21 +54ms service=state key=/app/input state disposal completed --- Initial command finished (exit code: 0) --- --- no_shell=true, exiting container without starting shell --- Command execution complete.
