My testall just finished on bsd.math and I get the same failures.

The result is wrong :) - William did fix some issue with integration
in the maxima wrapper, so this is a likely bug introduced there.

The doctest is new, so I am hoping that the sequence of the result is
just wrong, not the result itself. malb, any idea?

I see the exact same thing. This is only a guess, but it looks like a
potential precision issue now that we no longer use maxima to get a
numerical approximation of sqrt, but use mpfr. The result certainly
looks very close to the expected, but some expert on continued
fraction should tell us more.
