 When the findChild call is not done this code does not leak. So the leak

 be doing something wrong.
 
 In older version 4.7.3-2 this leak was not there.

Fixed in tonight's snapshot - thanks.

 [PyQt] Leak found in PyQt version 4.8.5-1 / 4.8.5 win32 build

 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.
