Hi Lars,

this is good information!
Since you don't get crashes from using stackless features, it is
pretty clear that the problems must come from things that
I changed to support stackless features.

Good to know.
Still, it would be nice if we had something more deterministic to
cause a crash, especially a crash that occurs without manual
interaction...

I think to have a closer look into PySide itself, to see if it uses
structures which are not officially public.

One thing would be interesting but involves tome work:
Can you install PyQt instead and try the same?

thanks & cheers - chris

I am also working with a combination of PySide 1.1.2 (same installer, but the 1.1.1 version had the same problem) and stackless 2.7 on windows and have to agree that it is pretty unstable. It is hard to find a pattern in the crashes and i do not even know whether i have the same problem, only that the crashes come and go, even when i do not change anything significant to the code. It also happens when i do not call any code that uses stackless explicitely (no tasklets are created in the portion of code that is actually run, apart from the main one I guess). Sometimes i get "unknown opcode" exceptions; could that be related?

It would be very helpful and comforting for the future of my project if this were resolved. If I can help, let me know ...

Cheers, Lars

    I installed PySide-1.1.2.win32-py2.7.exe which I downloaded from the
    PySide website.  It uses QT 4.8 going by the PyPI page.

    Yes, sdi.py, like most examples crashes on exit for me.  But every
    example I recall trying crashed in much the same way.



    Cheers,
    Richard.
