lds, search/6, no variables

Hi,

lds in search/6 has problems with an empty list of variables:

 ECLiPSe Constraint Logic Programming System [kernel]
 Version 5.8 #84, Tue Mar  1 00:17 2005

 [eclipse 1]: lib(ic).
 Yes (0.34s cpu)

 [eclipse 2]: Vars = [], search(Vars, 0, input_order, indomain, lds(2), []).
 out of range in shelf_create(lds / 0, 0, _257)
 Abort


Cheers,
Sebastian
