A217626_vec(n,{B=10})={my(u=n!-1);my(x=numtoperm(n,0),y,z=vector(u),i);for(j=1,u,y=numtoperm(n,j)-x;z[i++]=fromdigits(vector(#x-1,k,vecsum(y[1..k]) ) ,B);x+=y);z}

Hello Remy, it is a bug in the implementation of the -g option of gp2c.
But you can avoid the issue and improve your code by replacing
my(x=...,i);
by
my(x=...,i:small=0)

Cheers,
Bill.
