#               
#                   Confirmed bug on 4.0.0.2453, got:
#                       Statement failed, SQLSTATE = 27000
#                       unsuccessful metadata update
#                       -GRANT failed
#                       -action cancelled by trigger (0) to preserve data integrity
#                       -User cannot write to RDB$USER_PRIVILEGES
#                       -At procedure 'SP_TEST' line: 3, col: 8

#                   ::: NB ::: 22.05.2021
#                   This test initially had wrong value of min_version = 4.0
#                   Bug was fixed on 4.1.0.2468, build timestamp: 06-may-2021 12:34 thus min_version should be 4.1
#                   After several days this new FB branch was renamed to 5.0.
#                   Because of this, min_version for this test is 5.0
#                
# tracker_id:   
# min_versions: ['5.0']
# versions:     5.0
# qmid:         None
