Suppression of Last Error

By default, runtime checking suppresses the most recent error to prevent repeated reports of the same error. This is controlled by the dbx environment variable rtc_auto_suppress. When rtc_auto_suppress is set to on (the default), a particular access error at a particular location is reported only the first time it is encountered and suppressed thereafter. This is useful, for example, for preventing multiple copies of the same error report when an error occurs in a loop that is executed many times.
