V7 icheck and dcheck declare blist and ilist respectively with one
element too few.  Both arrays need an extra element for an end marker.
The effect is that `icheck -b b1 b2 b3 ... b10 filesystem' will dump
core.  Increasing the size of these arrays from NB to NB+1 fixes this
problem.  While you are at it, increase NB from 10 to something like
40, so that an entire track on most disks may be checked at once.
