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 2025-10-30T17:09:39 +4726ms service=default version=0.15.11

I will use the `todoread` and `todowrite` tools to manage the process of fixing each file, ensuring I address all constraints (compilation, sanitizers, correct output). Here is the plan: 1. **Create a Todo List** for all 8 files. 2. **Process each file sequentially:** a. Read the file content. b. Analyze the code to identify the subtle bug. c. Determine the fix. d. Apply the fix using the `edit` tool. e. Compile and run the fixed code with sanitizers using `bash` to verify the fix. f. Mark the task as `completed` and move to the next. I will start by creating the todo list.
