Does it always fail that test in the same way? I can't replicate
the problem on my 32-bit Linux RHEL5 machine:
[EMAIL PROTECTED] sage-2.8.4.1]$ ./sage -t
devel/sage/sage/plot/plot3d/transform.pyx
sage -t devel/sage-main/sage/plot/plot3d/transform.pyx
[6.9 s]
----------------------------------------------------------------------
All tests passed!
Total time for all tests: 6.9 seconds
Are you using RHEL5 or something else?
This test is from a new doctest Robert Bradshaw just added that illustrates
how to use the symbolic code in SAGE to compute transformation
matrices, but there error indicates that there was probably a problem
with the communication/synchronization between SAGE and Maxima
via pexpect.
