    Default Crashing without debug mode- No crashing with gdb debugger

    Dear All
    I am facing some problem in implementing a QScrollArea. I subclassed it and created a buttin on this as below.

    CScrollArea::CScrollArea() {
    printbutton = new QPushButton("Save As Image",this);
    printbutton->setGeometry(actual_page_width + coordx-100,coordy,100,25);
    connect(printbutton,SIGNAL(clicked()),this,SLOT(go toprinter()));
    }

    the problem is that when I am trying show this scrollarea through menu click its crashing. and crashing at the first line
    printbutton = new QPushButton("Save As Image",this);

    but when I am debugging this through gdb debugger then its running fine and at the end i can see the scroll are with button.

    Why is happening like this. Any idea from anyone would be highly appreciate.
    Also when I try to set a window title like
    setWindowTitle("My Page");
    its again crashing.
    Thanks in advance for any help. sujan

    Give us a compiling example reproducing the problem. It may clarify things.

    Also, did you try a full rebuild?

    You may also have to check if this actually exists. When attaching a debugger values are initialized differently.
