far from done.

? setrand(1);rnfkummer(bnrinit(bnfinit(y^6-19*y^5-11*y^4-6*y^3-15*y^2-11*y+15,1),4,1),[2,1,1;0,1,0;0,0,1]);
  ***   the PARI stack overflows !
  current stack size: 8000000 (7.629 Mbytes)
  [hint] you can increase GP stack with allocatemem()

Before, would finish at 4MB stack.

? bezoutres(Pol(sin(x)+Pi),Pol(cos(x)));
  ***   bug in subresext, please report

? setrand(2);rnfkummer(bnrinit(bnfinit(quadpoly(-6580,y)),9,1),matdiagonal([3,1,1,1]));

Still there.

Also, I have compilation problem on FreeBSD, wrong timing reporting in
galoisinit(), 1 round4 bug and 1 bnrstark() bug - Xavier is aware of
the last 2.
