Popped up in Sage 7.4.beta2 (or probably some earlier beta):

sage -t --long src/sage/libs/gap/  # 1 doctest failed
sage -t --long src/sage/symbolic/function.pyx  # 1 doctest failed

The first is the usual failure, the second is new, and I don't know
where it originates from (as the doctest itself hasn't changed):

File "src/sage/symbolic/function.pyx", line 667, in
Failed example:

(Native build on Haswell.)
