Throws a system error. Used when runtime execution can no longer proceed. For example, an exception is thrown without an active catcher. This built-in method is declared private and thus cannot be used as a message to an object. Calling this predicate is equivalent to the following sequence of goals:
..., context(Context), throw(error(system_error, Context)).
This allows the user to generate errors in the same format used by the runtime.
