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 2025-12-15T20:15:39 +7291ms service=default version=1.0.155

2025-12-15T20:15:48 +11ms service=default e=NotFoundError rejection Since this is a multi-stage, multi-file bug fixing task that requires compilation and verification, I will use the `task` tool with the `general` subagent to manage the process autonomously. I will first create a comprehensive plan by listing all the files and the general nature of the task (C++ bug fixing with specific compilation/sanitizer requirements). I will instruct the agent to: 1. Analyze the files provided. 2. For each file, use `bash` to attempt compilation with the strict flags (`-Wall -Wextra -Werror`) and run any included test/sanity checks to identify the initial error (compilation or sanitizer/logic error). 3. Identify and fix the single subtle bug in each file to satisfy all three original requirements. 4. Confirm a successful compilation and correct logic execution before moving to the next file. 5. Since the files are in `/app/input`, I will instruct the agent to work in that directory. This is a complex, multi-step task requiring autonomous decision-making, so the `task` tool is appropriate. Here is the initial plan for the agent: 1. List and read the content of all eight C++ files to understand their purpose and initial bugs. 2. For each file, attempt to compile with strict flags (`g++ -Wall -Wextra -Werror -fsanitize=address,undefined -std=c++17 -o `). 3. Identify the single bug (compilation error, sanitizer error, or logic error) and fix it in-place using the `edit` tool if necessary for minor single fixes, or propose the complete fixed file content via the `write` tool if the context of the fix is complex. Since I must modify the file in place, I will rely on the agent to use `edit` or `write` after investigation. 4. After fixing, re-run the compilation and potentially a logic check (if a simple driver/main is available or can be inferred) to ensure all three criteria are met. I will initiate this with the `task` tool, asking the agent to perform the entire process. Note: The user instructed me to *not* have a back-and-forth, so I must try to resolve this completely in one autonomous run using the `task` tool. First, I will list the files to confirm their presence and structure.
