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 2025-10-29T17:06:56 +6263ms service=default version=0.15.11

2025-10-29T17:07:18 +35ms service=bus type=message.part.updated publishing  I understand the task. I need to fix one subtle bug in each of the eight provided C++ files located in the `input/` directory. The fixes must ensure the code compiles cleanly with strict flags (`-Wall -Wextra -Werror`), passes sanitizer checks (ASan/UBSan), and produces the correct output. Since I cannot interact with a user, I must proceed autonomously based on the instructions. I will start by listing the files to confirm their presence and then tackle them one by one, starting with `virtual_destructor.cpp`. I will use the `bash` tool to compile and check each file after modification. First, I will list the files in the `input/` directory.
