Hello, the following piece of code leaks:
import PyQt4.QtGui import PyQt4.QtCore import time app = PyQt4.QtGui.QApplication([]) mainWindow = PyQt4.QtGui.QMainWindow() while True: button = PyQt4.QtGui.QPushButton(mainWindow) button.parent().findChild(PyQt4.QtCore.QObject, "foo") button.setParent(None) time.sleep(0.01) When the findChild call is not done this code does not leak. So the leak cause seems to be located somewhere in the findChild processing, or I must be doing something wrong. In older version 4.7.3-2 this leak was not there. Best regards. Carl.
