Memory Leak in Qt 4.7.3



  • Hello,
    We are using Qt 4.7.3 based GUI application. QML and cpp both using our application. When our application is running 60 - 62 days continue then we are facing memory leak. Memory leak is gradually increase.
    To Find out this issue I run my application with Valgrind. After some time I quit my application and observe Valgrind Output. I found from Valgrind output in some function definitely lost. I also found that some of QT function call more than two or three time in valgrind where it is definitely lost is there. Below is function that is called more than two times.

    1. QTextEngine::width(int, int)
    2. QDeclarativeComponentPrivate::completeCreate()
    3. QTextLine::layout_helper(int)
    4. QDeclarativeText::geometryChanged(QRectF const&, QRectF const&)
    5. QGtkStylePrivate::initGtkWidgets() const

    All above function it is showing definitely lost in it. From valgrind output also found that below flow is common.

    ==29294== 888 (256 direct, 632 indirect) bytes in 1 blocks are definitely lost in loss record 7,577 of 7,904

    There are two question

    1. Is there any Qt Library function issue or else ?
    2. If Qt Library Function Issue then what is solution for it ?

    Please help me if any one know about it.

    Below is Valgrind Output.
