polrootspadic bug?


Using:

GP/PARI CALCULATOR Version 2.2.1 (alpha)
UltraSparc (MicroSparc kernel) 32-bit version
 
the following happened:

(14:34) gp > polrootspadic(x^3+25920*x+746496,2,37)
%1 = [2^4 + 2^5 + 2^6 + 2^7 + 2^8 + 2^9 + 2^11 + 2^13 + 2^14 + 2^18 + 2^19
+ 2^20 + 2^21 + 2^22 + 2^23 + 2^26 + 2^27 + 2^28 + 2^31 + 2^33 + O(2^37)]~
(14:34) gp > polrootspadic(x^3+25920*x+746496,2,38)
^C  ***   user interrupt after 3mn, 16,783 ms.
(14:38) gp >

The second call to polrootspadic above seems to cause gp/pari to hang
indefinitely.  I encountered identical results under version 2.1.0 on
UltraSparc and on Linux.  Any idea what's happening? 

All the best,

Mark
