> Yes I can reproduce all these diffs outside sage so it is not a problem
of the spkg. For the loss in precision I have reported it on xcas forum to
know if it is a long term change or a bug so I wait a little to know if it
should be changed in giac.py.
you can just set up higher tolerance in the corresponding doctests.

did you check in
http://www.sagemath.org/doc/developer/coding_in_cython.html#interrupt-and-
signal-handling
It could be that things got changed there since 5.11 (I don't know for
sure; ask on sage-develop if problems persist here). Do you do `sign_on`
and `sign_off` ?
