Comment(by kcrisman):
Dan, thanks for that confirmation of the issue.
Replying to [comment:44 vbraun]:
> I'm still confused what, if any, issue remains. This patch only touches
the capture of the whole maxima output string, and not the parsing of
expression. If maxima's output ordering has not changed yet some platform
returns a different output sort order then this is an unrelated bug in the
maxima interface.

Actually, I'm pretty sure it's an unrelated bug in something else. At
first I thought Pynac/Ginac, but maybe not (?) - in Sage 4.6 on PPC, I get
{{{
sage: psi(1,1/3)*log(3)
log(3)*psi(1, 1/3)
sage: from sage.misc.citation import get_systems
sage: get_systems('psi(1,1/3)*log(3)')
['GMP']
}}}
This machine doesn't have the new Maxima, so it's definitely unrelated.
Nonetheless, we can't ship a Sage with a failing doctest that we know
about, except at great need - this is why I put needs work. The very
minor change in how Maxima grouped the coefficient of `x^3` created this.
So I recommend that we replace this doctest with something very similar
which doesn't have this problem, and then open a new ticket for this
issue. Maybe something like
{{{
sage: taylor(gamma(1/4+x),x,0,3)
}}}
except I can't tell you what the Mac output is on this until tomorrow -
maybe someone else can.
The new ticket is #10282.
