This mechanism is deprecated. Please use the new error handler mechanism instead.
If a method call cannot be dispatched, an error handler is called with a
reference to a method_call_error structure, which contains the method’s name
in an unspecified format, and a code identifying the error.
The default error handler terminates the program with abort(). A different
handler can be installed with set_method_call_error_handler, which returns the
previous handler. The handler may not return. It may throw an exception.
