Memory leak(s) found for the QDate object created with the fromString(const QString &string, const QString &format, QCalendar cal = QCalendar()) static method.

[Vilcrow]

OS: Ubuntu 22.04.01.
CppUTest: system installed version.
Qt: qtbase5.

For this case, everything is fine:

TEST_GROUP(DateGroup)
{
    QDate *date;

    void setup()
    {
        date = new QDate(2020, 10, 10);
    }

    void teardown()
    {
        delete date;
    }
};

TEST(DateGroup, Foo)
{
    CHECK(date->isValid());
}

but if we create the date with the fromString(const QString &string, const QString &format, QCalendar cal = QCalendar()) static method:

TEST_GROUP(DateGroup)
{
    QDate *date;

    void setup()
    {
        date = new QDate(QDate::fromString("10-10-2020", "dd-MM-yyyy"));
    }

    void teardown()
    {
        delete date;
    }
};

TEST(DateGroup, Foo)
{
    CHECK(date->isValid());
}

we will get the following:

error: Failure in TEST(DateGroup, Foo)
