For me (using octave 3.2 on ubuntu 10.04, sage 4.5.2a1) it ran on repeating
Exception RuntimeError: RuntimeError('maximum recursion depth exceeded
in cmp',) in Exception RuntimeError: 'maximum recursion depth exceeded
in __subclasscheck__' in <type 'exceptions.RuntimeError'> ignored
and refused to respond to ctl-c or ctl-d. I had to kill it using a kill -9 PID.
What did your system do?
