Re: gEDA-user: drc2 crash

   OK I have fixed my problem (well my scheme problem at least) by adding
   this line to the beginning of the gnet-drc2.scm file:
   ;; Give us more stack space
   (debug-set! stack 200000)
   I don't know if there is a better fix.

   Subject: 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:

     my list is so long it is crashing gnetlist.  I suspect this is

     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?
