# 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.

Perfect! I've successfully fixed all 8 C++ files. Here's a summary of the bugs that were fixed:

## Summary of Fixes

1. **virtual_destructor.cpp**: Added `virtual` keyword to the base class destructor to ensure proper cleanup of derived class resources.

2. **reference_to_temporary.cpp**: Changed return type from `const std::string&` to `std::string` to avoid returning a reference to a temporary object.

3. **iterator_invalidation.cpp**: Replaced iterator-based loop with index-based loop using the original size to avoid iterator invalidation when modifying the vector during iteration.

4. **unsigned_underflow.cpp**: Added proper handling for the ring buffer's `available()` method to account for wrap-around when `tail_ < head_`.

5. **dangling_cstr.cpp**: Changed return type from `const char*` to `std::string` to avoid returning a dangling pointer to a temporary string's c_str().

6. **init_order.cpp**: Reordered member variable declarations so `scale_` is declared first, matching the initialization order and preventing use of uninitialized values.

7. **off_by_one.cpp**: Changed loop condition from `i <= 5` to `i < 5` to prevent array out-of-bounds access.

8. **int_overflow.cpp**: Changed return type to `long long` and added cast to prevent integer overflow with large multiplication results.

All fixes address memory safety, undefined behavior, and correctness issues that would be caught by sanitizers and strict compiler warnings.
