Question

C++ Memory Leaks: Detection, Integration, and Prevention

You are building or maintaining a C++ service/library and need a practical approach to find and prevent memory leaks across platforms.

Discuss:

Dynamic analysis tools and options
- Linux: Valgrind/Memcheck; AddressSanitizer (ASan) and LeakSanitizer (LSan)
- Windows: Visual Studio AddressSanitizer, CRT debug heap, Diagnostic Tools
- macOS/iOS: Xcode Instruments (Leaks/Allocations), command-line leaks
Runtime/reporting integration
- How to run these tools in local dev, test, and CI
- How to fail builds/tests on leaks
- Using suppressions and mid-run leak checks
Preventive techniques
- RAII
- Smart pointers (unique_ptr/shared_ptr/weak_ptr)
- Ownership rules and coding practices
