I am using sip to generate python bindings for my c++ library. sip is also used to generate python bindings for the Qt Gui toolkit. The PyEval_*Thread and PyThreadState_* seem to end up with a NULL tstate parameter at different points of execution when I start instantiating more complicated sip-wrapped widget classes along with my own multi-threaded library. At one point, I moved the thread creation code into python (by causing it to simply call a method in my library to execute the thread), and it helped a bit.

I'm obviously not looking for help with sip, but it would be nice to get a general overview of what conditions cause a NULL tstate to be passed to these functions. I've posted a few messages on the sip mailing list about this, but the problem seems a little too biased toward the scope of this list for any of them to answer.

Actually, this is probably more appropriate for comp.lang.python; that's where usage questions belong, even usage questions about the API internals. If you're sure there's a bug, file a report on SF (with as minimal a testcase as possible), then report it here. -- Aahz (aahz@pythoncraft.com) <*> http://www.pythoncraft.com/ "Argue for your limitations, and sure enough they're yours." --Richard Bach
