    Description

      The regular expression lookbehind assertion IS fixed length, yet QRegularExpression fails, claiming it is not fixed.

       

      QRegularExpression tr = QRegularExpression("(?<=face=\"Times\" color=\"green\"><i>\()(.*?)(?=\)<\/i><\/font><\/td><\/tr>)");
qWarning() << tr.isValid() << tr.patternErrorOffset() << tr.errorString(); // false 0 "lookbehind assertion is not fixed length"
