    Default Runtime error: Invalid parameter passed to C runtime function.

    Hello.

    I am writing an editor for lua scripts of a specific game using QScintilla. I have written a stand-alone class (the class name is LuaEditor) for the editor widget. Inside mainwindow.h I have written this function to help me get the instance of the MainWindow so I can change some of its properties through the LuaEditor class:

    Cpp Code:
    1. static MainWindow *getInstance()
    2. {
    3. static MainWindow window;
    4. return &window;
    5. }
    To copy to clipboard, switch view to plain text mode 

    On LuaEditor class there's a function, newFile(), which initializes the editor widget...the code of the newFile() function is this:

    Cpp Code:
    1. void LuaEditor::newFile()
    2. {
    3. isUntitled = true;
    4. currentFile = "newScript.lua";
    5. MainWindow::getInstance()->setWindowTitle(tr("QtLuaPad - %1").arg(currentFile));
    6. setText(tr("-- Created using QtLuaPad on %1\n\nfunction onUse(cid, item, frompos, item2, topos)\n\treturn TRUE\nend").arg(QDate::currentDate().toString()));
    7. connect(this, SIGNAL(textChanged()), this, SLOT(setDocumentModified()));
    8. }
    To copy to clipboard, switch view to plain text mode 

    When I am trying to run the application (release mode), the application crashes and I get the following error:
    Invalid parameter passed to C runtime function.
    C:\Qt\Projects\QtLuaPad-build-desktop\release\QtLuaPad.exe exited with code 3
    and also this error msgbox:
    The application has requestes the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.
    Anybody knows what's going on here? I can provide you with the full source code in case you need it to solve my case. Thanks in advance.

    Yours,
    Delirium.

    It would be more useful if you tried reproducing the same behaviour with a minimal compilable example.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.
