Wow, that is an amazing response, thank you so much for that quick turnaround.  Will download the 3.2.16 package and give it a go.

I think I have solved this. My debug runs in 2.7 & 3.4 are now OK. For some reason I was playing about with the module traverse and clear mechanisms and had put in a reference to moduleVersion in there and also added it to the module object state. Calling Py_CLEAR on that was wrong, but it seems easier to remove the unwanted reference to the module version from the state and then things are working fine without tp_traverse or tp_clear funcs in the python 3 module object.

I have bumped the _rl_accel version to 0.71 and you can find the code on bitbucket if you want to stick with 3.2.0; other wise the latest tar zips etc etc are at


version 3.2.16 is what you want.

Thanks for the bug report.
