ISSUE:       4760
TITLE:       ISQL crashed without connect when execute command "show version"
DESCRIPTION:
JIRA:        CORE-4440
FBTEST:      bugs.core_4440
NOTES:
    [12.12.2023] pzotov
    Added 'Error reading/writing' 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 message related to any error.
