# decription:   
#                   Confirmed bug on 4.0.0.2076, 3.0.6.33322
#                   Checked on 4.0.0.2078, 3.0.6.33326 - all OK.
#                   (intermediate snapshots with timestamps: 26.06.20 06:36, 07:26)
#               
#                   27.07.2021: separated code for FB 4.x+ because of fix #6874
#                   ("Literal 65536 (interpreted as int) can not be multiplied by itself w/o cast if result more than 2^63-1"):
#                   no more error with SQLSTATE = 22003 after this fix.
#                   Checked on 5.0.0.113, 4.0.1.2539.
