[Pyobjc-dev] PyObjC: Non-aligned pointer being freed

[Bob S. <rsw...@tr...>]

I'm getting these error messages from by PyObjC (version 1.0) application:

PyObjCPointer created: at 0x208aaa0 of type
{_NSModalSession=@@^{_NSModalSession}iciI^vi@@:^vi}
*** malloc[1763]: error for object 0x379174: Non-aligned pointer being freed

The offending code is:

    alertPanel = None
    modalSession = None
    application = MyApp.Application # bound to "File's Owner" in
InterfaceBuilder
    try:
        alertPanel = NSGetInformationalAlertPanel("Please wait", None, None,
None)
        modalSession = application.beginModalSessionForWindow_(alertPanel)
        ...other code...
    finally:
        if modalSession != None:
            application.endModalSession_(modalSession)
            modalSession = None

        if alertPanel != None:
            NSReleaseAlertPanel(alertPanel)
            alertPanel = None

I posted this earlier in the summer, but did not get a response - I had
hoped that the 1.0 release would fix it, but it did not.

Am I using the modal code correctly with PyObjC?  How do I avoid this error?

Many thanks,
