ISSUE:       5843
TITLE:       Bugcheck on queries containing WITH LOCK clause
DESCRIPTION:
  We create database as it was show in the ticket and do backup and restore of it.
  Then we run checking query - launch isql two times and check that 2nd call of ISQL
  does not raise bugcheck. Finally we run online validation against this DB.

  Neither test query nor validation should raise any output in the STDERR.
