Access violation when using QWebView (Qt 4.8.0)

  • Hi.
    I've built Qt in Visual Studio 2008 SP1 with compile option /Zc:wchar_t.
    After calling setUrl method in debug configuration there comes an access violation error
    I've created a blank test qt application project with single component (QWebView).
    setUrl method is called from Ui_bugTestClass::setupUi function in the generated file ui_bugTest.h

    In release configuration QWebView is also working fine.
    The same project with qt 4.7.4 is also working fine.

    What am I doing wrong?

  • Try confirm if all dependencies are ok.

    "Frames below may be incorrect and/or missing, no symbols loaded"


  • I've checked, the dependencies are ok
    If any dependence is wrong, the application will start with dll loading error
    “Frames below may be incorrect and/or missing, no symbols loaded” - Visual Studio could not load the debug symbols, the dependencies dont come in

  • It seems that this is a bug!!!

  • If so, please file a "bug report": and don't forget to link it here.

  • Sorry, it was an unsuccessful build.
    Full rebuild works well.
