ILT problem



I have two sets of data with almost the same values ilt works with one 
of them and not the other.
Why?
you can get the file here
Dougs.homeip.net/bug2.mac

or cut and paste this:



q:2*(5.5*s^2+36.25380116959065*s+63.76900584795322)/(s*(s^2+4*s+3)*(2*(5.5*s^2+36.25380116959065*s+63.76900584795322)/(s*(s^2+4*s+3))+1));


ilt(q,s,t);




w:2*(5.499925*s^2+36.25304548599101*s+63.76708977768073)/(s*(s^2+4*s+3)*(2*(5.499925*s^2+36.25304548599101*s+63.76708977768073)/(s*(s^2+4*s+3))+1));

ilt(w,s,t);

q works  w doesn't.

PS These are 2 different but almost the same  results from a much larger 
maxima program.
