[Stackless] strange bug with weakref on main tasklet

I wasn't able to repro using your code.  I tried compiling without object malloc and running within purify but no errors are reported.
I also tried to explicitly call gc.collect() to trigger a collection.

What I don't understand is why stackless.main() should be garbage collected at all?  The main tasklet should never die.

I suspect that there is something curious going on in the rest of the code that you have and the gc thing is just a red herring.  You can verify that by using your own weakref and hook into its deletion callback.  See if your tasklet is ever actually deleted and the weakref is cleared.

Perhaps you can supply me with the rest of the (crashing) module and I can give it a go with purify.
