What version are you using? I'm attaching a C++ test and his output, in my machine it leaks, but much more slowly than the previous python script. Also, the leak rate seems to be more constant than the python one. Is possible that a Qt bug is impeding pyqt to deallocate his objects, so the Qt leak get bigger by having attached the pyqt objects? Btw, if you want, I can provide ssh access to the machine where this bug happens. Ricardo: Maybe it will be helpful if you post your tests to the list. Saludos, Nahuel Greco.
