std with different representation of same ordering, one does not terminate

[ren]

The following orderings are the same, yet the last std computation does not finish while the first two do:

ring sds = integer,(t,x1,x2,x3,x4),ds;
ideal I = 3-t,2*x1^2+3*x1*x2+24*x3*x4,8*x1^3+x2*x3*x4+18*x3^2*x4;
std(I);

ring sws = integer,(t,x1,x2,x3,x4),ws(1,1,1,1,1);
ideal I = 3-t,2*x1^2+3*x1*x2+24*x3*x4,8*x1^3+x2*x3*x4+18*x3^2*x4;
std(I);

ring salp = integer,(t,x1,x2,x3,x4),(a(-1,-1,-1,-1,-1),lp);
ideal I = 3-t,2*x1^2+3*x1*x2+24*x3*x4,8*x1^3+x2*x3*x4+18*x3^2*x4;
option(prot);
std(I);
