Greetings!

We've checked your source code with AppChecker (https://npo-echelon.ru/en/solutions/appchecker.php) static analyzer and found some bugs:

1)
https://github.com/apache/openoffice/blob/c014b5f2b55cff8d4b0c952d5c16d62ecde09ca1/main/rdbmaker/source/rdbmaker/rdbmaker.cxx#L113

while (*p == ' ' && *p =='\t')

\*p can' be equal to ' ' and '\t' at the same time - so the expression is always false.

(aValidation.aOperator == sheet::ConditionOperator_BETWEEN &&
            aValidation.aOperator == sheet::ConditionOperator_NOT_BETWEEN &&

This is the same thing as previous

 if(eHOrient != text::HoriOrientation::NONE || eHOrient != text::HoriOrientation::LEFT)


Expression is always true.
If eHOrient is equal to text::HoriOrientation::LEFT, then eHOrient != text::HoriOrientation::NONE -> the whole expression is true
If eHOrient is equal to text::HoriOrientation::NONE, then eHOrient != text::HoriOrientation::LEFT-> the whole expression is true
If eHOrient is equal to another value (text::HoriOrientation::RIGHT), then eHOrient != text::HoriOrientation::NONE -> the whole expression is true

if(eHOrient != text::HoriOrientation::NONE || eHOrient != text::HoriOrientation::LEFT || eHOrient != text::HoriOrientation::RIGHT)

Same as previous.

                    if(eHOrient != text::HoriOrientation::NONE || eHOrient != text::HoriOrientation::LEFT || eHOrient != text::HoriOrientation::RIGHT)

Same as previous, expression is always true.

if(eSurround != SURROUND_LEFT || eSurround != SURROUND_RIGHT)

Same as previous, expression is always true.
