Details:

Thankfully in Octave 6.1 all exception types are refactored to inherit
,directly or indirectly, from std::exception but it may need some modification
to be used in the following situation. Consider the following example:


try
  {
    error ("some error");
  }
catch (const std::exception& e)
  {
    std::cout << "can be caught with std::exception\n" ;
  }
catch (...)
  {
    std::cout << "cannot be caught with std::exception\n" ;
  }


Someone may want to throw an error and use std::exception to catch it but
currently it is impossible because the exception liboctave/util/quit.h is
defined as :


class execution_exception : std::runtime_error


This StackOverflow post https://stackoverflow.com/a/8152888/6579744 recommends
to define it as


class execution_exception : public std::runtime_error


Thanks!
