gEDA-user: drc2 crash



   I am attempting to run the drc2 check with gnetlist.  I have checked
   each individual schematic separately, and drc2 works fine.  But when I
   tried to run them altogether I am getting the following crash:
   In /sw/share/gEDA/scheme/gnet-drc2.scm:

   This appears to me to be a genuine stack overflow.  That is the in the

   my list is so long it is crashing gnetlist.  I suspect this is getting
   called from line 538:
              (if (> (drc2:count-reference-in-list refdes

   So the recursion makes it less than half way through my list.  I
   suppose I could disable dont-check-duplicated-references, but it is
   precisely these long part lists that make this feature useful.  Does
   anyone know of a work around?
