Well, we should at least be checking for an exception here anyways:

proc->me = PyCObject_FromVoidPtr(proc, NULL);
PyDict_SetItemString(PLy_procedure_cache, key, proc->me);

if (proc->me == NULL) complain();

That is, with those warnings adjustments, proc->me will be NULL and then explode in PyDict_SetItemString:

However, if someone overrides the process-wide warnings settings, then
the API can fail altogether, raising a PendingDeprecationWarning
exception (which in CPython terms means setting a thread-specific error
state and returning NULL).

AFA a better fix is concerned, the shortest route would seem to be to use the new capsule stuff iff Python >= 2.7.
