Comment (by jpflori):

 Another problem is that the bug seems to occur very rarely...

 I've not seen it yet on top of 5.1.beta0 + #12313 although I have the
 feeling it should occur (or I'm wrong :) ).

 Even on top of 5.0.beta13 + #715 + #11521 + #12313 it does not happen so
 frequently when looping over the tests of ell_tate_curve.

 I'll run some (I mean a LOT) test without #12313 now, just to be sure this
 is indeed the culprit.
