ISSUE:       5992
TITLE:       Unclear error message when inserting value exceeding max of dec_fixed decimal
DESCRIPTION:
    FB40SS, build 4.0.0.1008: OK, 1.641s.
    Previously used:
        create table extdecimal( dec34_34 decimal(34, 34) );
        insert into extdecimal values(1);
    -- and this raised following exception:
        SQLCODE: -901
        Decimal float invalid operation.  An indeterminant error occurred during an operation.
        numeric value is out of range
    ==================================
    Since 30.10.2019 DDL was changed:
      create table test(n numeric(38,38) );
      insert into test values( 1.70141183460469231731687303715884105727 ); -- must PASS
      insert into test values( 1.70141183460469231731687303715884105727001 ); -- must FAIL.
    Explanation:
      1.70141183460469231731687303715884105727 represents
      2^127-1 // 170141183460469231731687303715884105728-1

    Checked on:  4.0.0.1635
JIRA:        CORE-5726
FBTEST:      bugs.core_5726
NOTES:
    [25.06.2020] pzotov
        4.0.0.2076: type in SQLDA was changed from numeric to int128 
        (adjusted output after discussion with Alex about CORE-6342).
    [13.12.2023] 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.
