    Description

      #include <QDebug>
#include <QRegularExpression>
#include <QString>

int main(int argc, char *argv[])
{
    const QRegularExpression expr("\\s+");
    const QString str("Foo Bar Blubb");
    qDebug() << str.lastIndexOf(expr, -7);
}

      prints 7 instead of the correct 3.

      I'd suspect https://codereview.qt-project.org/c/qt/qtbase/+/325907 (though I haven't tried to confirm that).
