ISSUE:       6874
TITLE:       Literal 65536 (interpreted as int) can not be multiplied by itself w/o cast if result more than 2^63-1
DESCRIPTION:
  Confirmed need to explicitly cast literal 65536 on: 5.0.0.88, 4.0.1.2523 (otherwise get SQLSTATE = 22003).
FBTEST:      bugs.gh_6874
NOTES:
    [14.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
