Doctest Issues with Sage 3.0.5 on Solaris x86

File "/home/mabshoff/sage-3.0.5-x86-solaris/tmp/calculus.py", line 2394:
    sage: integral(x^n,x)
Expected:
    Traceback (most recent call last):

    TypeError: Computation failed since Maxima requested additional constraints (use assume):

Got:
    Maxima crashed -- automatically restarting.

a.divided_difference([3,2,1]) leads to
    X[1]
function: nullp(1)
enter a to abort with core dump, g to go, f to supress
s to supress further error text, r to retry,  e to explain, else stop
ERROR: empty object as parameter?:
            sage: X = SchubertPolynomialRing(ZZ)
            sage: a = X([3,2,1])
            sage: a.divided_difference(1)
            X[2, 3, 1]
            sage: a.divided_difference([3,2,1])
            X[1]

But we get the correct result by going on: 

sage: X = SchubertPolynomialRing(ZZ)
sage: a = X([3,2,1])
sage: a.divided_difference([3,2,1])
function: nullp(1)
enter a to abort with core dump, g to go, f to supress

This is likely numpy. 

from sage.rings.qqbar import ANRoot
x = polygen(QQbar)
intv = CIF(RIF(0, 1), RIF(0.1, 1))
rt = ANRoot(x^5 - 1, intv)
*boom*

Probably a numpy problem according to cwitty.

With Mike Hanson's help we can reproduce this in pure numpy: 

-bash-3.00$ ./sage -python
Python 2.5.2 (r252:60911, Jul 14 2008, 15:20:38)

>>> from numpy import *
>>> a = array([1,0,0,0,0,-1],dtype=complex)
array([ 1.+0.j,  0.+0.j,  0.+0.j,  0.+0.j,  0.+0.j, -1.+0.j])
>>> roots(a)
/home/mabshoff/sage-3.0.5-x86-solaris/local/bin/sage-sage: line 359: 20900 Segmentation Fault      (core dumped) python "$@"

And it is still broken in numpy 1.2.rc1 - see this thread on the numpy discussion list
