    <div class="moz-cite-prefix">Hi Lars,<br>
      <br>
      this is good information!<br>
      Since you don't get crashes from using stackless features, it is<br>
      pretty clear that the problems must come from things that<br>
      I changed to support stackless features.<br>
      <br>
      Good to know.<br>
      Still, it would be nice if we had something more deterministic to<br>
      cause a crash, especially a crash that occurs without manual<br>
      interaction...<br>
      <br>
      I think to have a closer look into PySide itself, to see if it
      uses<br>
      structures which are not officially public.<br>
      <br>
      One thing would be interesting but involves tome work:<br>
      Can you install PyQt instead and try the same?<br>
      <br>
      thanks & cheers - chris<br>

      (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?

              Yes, sdi.py, like most examples crashes on exit for me.
