Comment:
I get a LOT of timeouts on PPC OS X 10.4. I think that basically any time
Maxima is invoked inside Sage, it times out or does something else weird.
E.g.
{{{
sage: integrate(x^2,x)
Exception RuntimeError: 'maximum recursion depth exceeded in
__subclasscheck__' in <type 'exceptions.RuntimeError'> ignored
Exception RuntimeError: RuntimeError('maximum recursion depth exceeded in
cmp',) in Exception RuntimeError: 'maximum recursion depth exceeded in
__subclasscheck__' in <type 'exceptions.RuntimeError'> ignored
ignored
Exception RuntimeError: 'maximum recursion depth exceeded in
__subclasscheck__' in <type 'exceptions.RuntimeError'> ignored

cmp',) in Exception RuntimeError: 'maximum recursion depth exceeded in

ignored

__subclasscheck__' in <type 'exceptions.RuntimeError'> ignored
Exception RuntimeError: RuntimeError('maximum recursion depth exceeded in
cmp',) in Exception RuntimeError: 'maximum recursion depth exceeded in
__subclasscheck__' in <type 'exceptions.RuntimeError'> ignored
ignored
}}}
I also get the following:
{{{
sage -t -long "devel/sage/sage/calculus/functions.py"
**********************************************************************
File
"/Users/student/Desktop/sage-4.6/devel/sage/sage/calculus/functions.py",
line 46:
sage: wronskian(*[x^k for k in range(1, 5)])
assert len(self._before())==0, 'Maxima expect interface is
confused!'
AssertionError: Maxima expect interface is confused!
}}}
What the heck? I assume the change to the Maxima interface is to blame;
reverting that patch only (not the doctest one) seems to fix the problem.
Though in that case I do get
{{{

which is interesting; if you find where they differ (hint - transposed
multiplication), you win the Where's Waldo award.
I'll report back if there are any other errors without it.
