In analogy to "--cassert" and "--debug", one could add a "--null-paranoid" option :) that would make that macro defined. That would be no slowdown for non-paranoids and a friendly error reporting for paranoids. Though I'm not sure if it is worthwhile of maintenance effort and falling back onto core dump would always "work". -s
