#396: poly1d hangs

 from numpy import *

 p = poly1d([nan,nan,1], r=0)

 p.r

 The last command makes python hang, not even CTRL-C helps.
 In practice you don't give of course deliberately [nan,nan,1]
 as coefficients, but earlier in the code something may have
 gone wrong, so that the coefficients are not what is meant.
 I would expect then an ArithmeticError of poly1d rather than hanging.

 Versions: Python 2.5 + Numpy 1.0
