# title:        Bugcheck on queries containing WITH LOCK clause
# decription:    
#                  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.
#               
#                  Confirmed bug on 4.0.0.684 and 3.0.3.32743, got:
#                  ===
#                      Statement failed, SQLSTATE = XX000
#                      internal Firebird consistency check (decompression overran buffer (179), file: sqz.cpp line: 282)
#                      Statement failed, SQLSTATE = XX000
#                      internal Firebird consistency check (can't continue after bugcheck)
