Work in progress or progress in work? :)  I guess we need both:

? factor(polzagier(60,0));
  ***   bug in T==NULL in FpXQX_mul, please report
? rnfpolredabs(nfinit(quadpoly(197,y)),quadray(197,12));
  ***   bug in not a polynomial in FpXQ_invsafe, please report
? rnfpolred(nfinit(quadpoly(1297,y)),quadray(1297,1));
  ***   bug in GP (Segmentation Fault), please report

etc.

Thanks
