[Stackless] Strange crashes after channel send/receive

[Lloyd Weehuizen]

I'm having problems with totally trashed stacks after recent channel 
send/receives.

Python is embedded in my application and the main update loop calls into 
a python function that calls stackless.run() each update. Somewhere 
between the return of the python based update function and the calling C 
PyObject_CallObject it crashes with 0xcccccccc being the only thing on 
the stack.

As far as I can tell it gets triggered after the C++ app sends a message 
down a channel ( from the main tasklet ), stackless switches into the 
target tasklet, processes the event and switches back to the main 
tasklet... The main tasklet then does the stackless.run(), which 
executes all pending tasklets and then trashes the stack on its return 
into the main C++ code.

Does anybody have any tips on the best way to start debugging a problem 
like this? Is there a way to get more debugging information out of the 
stackless core?

Thanks
Lloyd
