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 2025-11-04T17:04:20 +7693ms service=default version=1.0.20

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 with strict warnings, passes sanitizer checks, and produces the correct output. I must modify the files in place and cannot ask for clarification. I will start by listing the files to confirm their existence and then proceed to analyze and fix them one by one. First, I will list the files in the current directory to confirm the structure.

I will now create a plan to address each file sequentially, starting with `virtual_destructor.cpp`. I will use the `read` tool to inspect the content of each file before attempting a fix, and then use the `edit` tool to apply the correction. I will use the `todowrite` tool to track the progress of these eight independent fixes. Here is the initial todo list: 1. Fix bug in `virtual_destructor.cpp` (memory management/plugin system). 2. Fix bug in `reference_to_temporary.cpp` (configuration system). 3. Fix bug in `iterator_invalidation.cpp` (event queue processor). 4. Fix bug in `unsigned_underflow.cpp` (ring buffer implementation). 5. Fix bug in `dangling_cstr.cpp` (log formatting system). 6. Fix bug in `init_order.cpp` (coordinate system with units). 7. Fix bug in `off_by_one.cpp` (matrix border detection). 8. Fix bug in `int_overflow.cpp` (bulk price calculator). 9. Verify all fixes by compiling and running tests/checks (if applicable/possible via bash). I will start with task 1.
