division by zero in intnum

I've been having trouble with intnum, and managed to distill it down to the following, which occurs in both 2.3.4 and the latest svn:

? intnum(r=[0.5,-1/2], 1, 1/sqrt(4*r^2-1))
  ***   at top-level: intnum(r=[0.5,-1/2],1,1/sqrt(4*r^2-1))
  ***                                        ^---------------
  *** _/_: division by zero

(It makes no difference whether the order of the singularity is specified or not.)
