 TITLE:       Interpretation of DECFLOAT values as BIGINT
 DESCRIPTION:
-  Check commit: "Fixed parsing of scaled integers and MAX/MIN INT64", 2017-05-28
-  See: github.com/FirebirdSQL/firebird/commit/1278d0692b535f69c7f9e208aad9682980ed9c59
-NOTES:
-[10.12.2019]
-  Updated syntax for SET BIND command because it was changed in 11-nov-2019.
-[30.12.2019]
-  Updated code and expected_stdout - get it from Alex, see letter 30.12.2019 16:15.
-[25.06.2020]
-  changed types in SQLDA from numeric to int128 // after discuss with Alex about CORE-6342.
-[01.07.2020]
-  adjusted expected output ('subtype' values).
-  Removed unnecessary lines from output and added substitution section for result to be properly filtered.
-
-  Found a problem with interpreting values
-  170141183460469231731687303715884105727 and -170141183460469231731687303715884105728
-  Sent letter to Alex (01.07.2020 13:55), waiting for fix. Check of bind DECFLOAT to INT128 was deferred.

+        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.
