My least favorite C++ feature
summary
Declares C++'s worst feature as memory unsafety and shows how an arbitrary write can overwrite function pointers or vptrs to yield arbitrary code execution, not just crashes. Names practical mitigations: clang CFI, Control Flow Guard, and ARMv8.3 pointer authentication used on Apple platforms, explains each limits exploiting indirect calls and often turns attacks into crashes. Recommends checking which CFI/PAC options the target platform and toolchain actually provide.
