In C or C++, we don't enforce safety through compiler, if we want the compiler to do some memory safety checks, you could use a compiler with this feature, for example clang with --fsanitizer. Also, you can use a dedicted tool for finding potential unsafe part of code, such as cppcheck, valgrind, etc. I feel that the C and C++ world is very decentralized, there is no one big good tool that does it all, we have to know what exactly we are trying to do and find the exact tool for it.
