gEDA-user: stack overflow with gnetlist -g drc

[Kai-Martin Knaak <kmk@xxxxxxxxxxxxxxx>]

An attempt to do a gnetlist -g drc on my current project yields a stack 
overflow error:

/-------------------------------------
kmk@kwak:~/geda/DL-strom$ gnetlist -g drc2 strom_0_master.sch -o drc_output.txt

Remember to check that your schematic has no errors using the drc2 backend.
You can do it running 'gnetlist -g drc2 your_schematic.sch -o drc_output.txt'
and seeing the contents of the file drc_output.txt.

\--------------------------------

A run of gsch2pcb on the same schematic is successful. So I suspect 
it is a bug in gnetlist rather than in my schematic. Anything I can 
do to help diagnose this illness?
