Linker symbol error with only debugger not run mode

  • Hi all,

    I've an error that is occuring on the slot function of QTableWidget::cellChanged. The following error message has been printed on the window of "application output" when I've started with debugger but there is not a problem when I started with "run". Is it a debugger error or coding error or Qt 4.8.4 bug? How can we explain the app is running without error message on run-mode?

    *can't find linker symbol for virtual table for `QTableWidgetItem' value found 'qt_enable_backingstore' instead

    Thanks advance for your helps and clarifications,
