The cmp() function and the C function PyObject_Compare() first try the new rich comparison operators before trying the old 3-way comparison.

The rich comparison func...

The callbacks don't trigger then, preventing the problems. If you need callbacks to trigger, then just as when cyclic gc is not involved, you need to write your code so that weakref objects outlive the objects they weakly reference. Critical bugfix, for SF bug 840829: if cyclic garbage collection happened to occ...
