ISSUE:       5336
TITLE:       Regression: incorrect calculation of byte-length for view columns
DESCRIPTION:
JIRA:        CORE-5049
FBTEST:      bugs.core_5049
NOTES:
    [12.12.2023] 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.
