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 2025-10-28T16:53:27 +3802ms service=default version=0.15.11

I will use the `todoread` and `todowrite` tools to manage the progress for each file. Here is the plan: 1. **Read** the contents of all C++ files to understand the code and the context of the bug. 2. **Analyze** each file for the single subtle bug based on the file name's hint (e.g., `virtual_destructor.cpp` suggests a missing virtual destructor). 3. **Fix** the bug in the file using the `edit` tool. 4. **Compile and Test** the fixed file using `g++` with the specified flags (`-Wall -Wextra -Werror -fsanitize=address,undefined`) and run the resulting executable to verify correctness. 5. **Repeat** for all 8 files. I will start by creating the todo list and reading the files.
