VC crash?

[DrD]

It seems like the coeff() command may only accept expressions with less than three variables. I don't know for sure. It may just be something quirky in my setup, but if you have the time and willingness to test this, I would like to find out if it crashes your Virtual Calc as well. coeff() seems to work fine as long as there are less than four variables in an expression: (You can copy and paste the command lines)

[CAS MODE]
L0:={"2x+y+2z","2x+y+2z+w"};
L1:={{x,y,z},{x,y,z,w}};

(VC Works ok)
coeff(CAS(L0(1)),L1(1));

(Crashes my VC)
coeff(CAS(L0(2)),L1(2));
