# title:        Database gets partially corrupted in the "no-reserve" mode
# decription:   
#                  Test uses .fbk which was created on 2.5.7.
#                  We restore this database and run validation using gfix (NOT fbsvcmgr!).
#                  Validation should not produce any output and new lines in firebird.log should contain
#                  only messages about start and finish of validation with zero errors and warnings.
#               
#                  Confirmed bug on 4.0.0.326, 3.0.1.32573. No errors on 4.0.0.328,  3.0.1.32575
