Test case for this bug

Crash occurs when native parent constructor is called before qobject's-one.

This one will crash:

class Worker(threading.Thread,QObject):
    def __init__(self):
        threading.Thread.__init__(self)
        QObject.__init__(self)

But this one will not crash:

class Worker(threading.Thread,QObject):
    def __init__(self):
        QObject.__init__(self)
        threading.Thread.__init__(self)

Test case attached to this issue.

Works for me on Linux, I'm going to test it on Windows.

Comment 2 Hugo Parente Lima 2010-10-20 11:25:54 EEST

Also works on Windows using git HEAD, so changing status to invalid.

Comment 3 Hugo Parente Lima 2010-11-25 17:53:38 EET
