I did not claim it was sufficient. But RTTI is needed to match catch handlers with exceptions. Consider: #include <vector> #include <string> #include <iostream> #include <exception> int main() { try { std::vector<std::string> tooBig(1UL<<31,"just some string"); } catch(std::exception& x) { std::cerr << "Failure: "<<x.what()<<std::endl; } } How would the C++ run-time handle a failure of this memory allocation without RTTI?
