C++ Undefined Behavior Returning from a [[noreturn]] function


Example

C++11

Example from the Standard, [dcl.attr.noreturn]:

[[ noreturn ]] void f() {
  throw "error"; // OK
}
[[ noreturn ]] void q(int i) { // behavior is undefined if called with an argument <= 0
  if (i > 0)
    throw "positive";
}
