I built Sage 4.1.1.rc0 on a sun4u machine using updated versions of Maxima (5.19.0) and ECL (9.8.1). There were 15 test failures. Here is one of them.
I've created a ticket. http://sagetrac.org/sage_trac/ticket/6716 sage -t "devel/sage/sage/functions/special.py" ********************************************************************** File "/export/home/drkirkby/sage/sage-4.1.1.rc0/devel/sage/sage/functions/special.py", line 1208: sage: elliptic_e(0.5, 0.1) Expected: 0.498011394499 Got: 0.497801100392 ********************************************************************** The result is similar to that expected, but not identical. I tried this in Mathematica 7.0 too, but using 1/2 instead of 0.5, and 1/10 instead of 0.1. Then asked for the result with 50 digits of precision. {{{ In[4]:= N[{{{ sage -t "devel/sage/sage/functions/special.py" ********************************************************************** File "/export/home/drkirkby/sage/sage-4.1.1.rc0/devel/sage/sage/functions/special.py", line 1208: sage: elliptic_e(0.5, 0.1) Expected: 0.498011394499 Got: 0.497801100392 ********************************************************************** }}} The result is similar to that expected, but not identical.
