生产环境下的实用安全性

The challenge of improving the memory safety of the vast landscape of existing C++ code demands pragmatic solutions. Standard library hardening represents a powerful and practical approach, directly addressing common sources of spatial safety vulnerabilities within the foundational components used by nearly all C++ developers. Our collective experience at Apple and Google demonstrates that significant safety gains are achievable with surprisingly minimal performance overhead in production environments. This is made possible by a combination of careful library design, modern compiler technology, and profile-guided optimization.
