Re: gEDA-user: Stack Overflow in gnetlist

["joe tarantino" <joeft@xxxxxxxxxxxxx>]

 

Matt,

 

Thanks for the pointer.  The suggestion in that posting worked.  Since my original posting I also started getting stack overflows in the "bom2" back end as well.

 

Just for the record, I inserted a line in gnet-bom2.scm and gnet-drc2.scm that looks like this:

 

 (debug-options (list 'stack 200000))

 

As the 2002 posting indicated, changing the parser is probably the correct fix, but that was beyond my abilities at this point.

 

Thanks again.

 

 Joe T

Many of the netlist backends are implemented with recursive functions,
so large schematics cause this.  The real solution is to rewrite them
as properly tail-recursive.  The interim solution is to adjust the
stack size to be much bigger:
