bug in poldegree?


hi at all,

on my system (debian) I use pari/gp 2.2.6 and the newest cvs-version
2.2.8. 

now, lets have a look at the following polynomial:

P=
(2.5134558550000000000000000000000000000000000000000000000000000000000000000000000 E-88 + 0.E-87*I)*y^2 + (1.0000000000000000000000000000000000000000000000000000000000000000000000000000000 + 0.E-86*I)*y + (1.6086117470000000000000000000000000000000000000000000000000000000000000000000000 E-86 - 1.6086117470000000000000000000000000000000000000000000000000000000000000000000000 E-86*I)

I got this polynomial from some computings under 2.2.8. if I want to
know

? poldegree(P)
= -2147483647

I get this strange degree, it should be 2.

under pari/gp 2.2.6 and the stable version everything is ok. 

is this a bug? 

cheers
