polredabs() bug

[Igor Schein <igor@txc.com>]

Hi,

polredabs() doesn't reduce the following polynomial:

x^8-2*x^7-34*x^6+78*x^5+265*x^4-628*x^3-389*x^2+1237*x-449

The correct answer is 

x^8-2*x^7-22*x^6+46*x^5+73*x^4-102*x^3-19*x^2+25*x+5

as returned by version 2.0.19 and earlier.

Thanks

Igor

P.S.

It's been a while since I found this sort of bug.  polredabs() has
grown to be very reliable for me.
