searchstack cannot be less than 8; if you set it to 4, it's going to be 
set to 8 anyway (and issue a warning).  However, when searchstack is set 
to 8 (instead of 16, the default), the amount of memory you're 
malloc'ing in that call (size=8388608, resulting from searchstach * 
sizeof(ID) * (2<<17)) should halve.  Are you sure you set the parameters 
as indicated above?
