Ok, got it. I think __ipow__ should be a ternaryfunc, like so:

diff --git a/Objects/typeobject.c b/Objects/typeobject.c
index 403f3caaee..914d076b5c 100644
--- a/Objects/typeobject.c
+++ b/Objects/typeobject.c

     IBSLOT("__imod__", nb_inplace_remainder, slot_nb_inplace_remainder,

     IBSLOT("__irshift__", nb_inplace_rshift, slot_nb_inplace_rshift,

On the other hand it is odd if "**=" can never use the third argument.
