# 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)
# ===
# Results after fix:
# fb30Cs, build 3.0.3.32746: OK, 6.328s.
# fb30SC, build 3.0.3.32746: OK, 3.469s.
