Docker installed C++ compilation will use gcc:13 Docker image to avoid host path conflicts --- TASK BEGIN --- # C++ Bug Hunt: Fix Subtle Errors You'll find several C++ files in the current directory. 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 the same directory). 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 2026-01-18T16:31:29 +1075ms service=default version=1.1.17

Since I cannot ask questions, I will proceed by analyzing and fixing each file sequentially, starting with understanding the environment and then attacking each file based on the bug category described.
