	Could you send me a schematic which displays this problem?
Does this happen on the gschem/example/*.sch schemtics?

	I haven't seen anything like this when running gschem on Linux.
Could you try the same tests under linux to see if this is a MacOSX
specific problem.

	It's primarily in libgeda/noweb/m_basic.nw

	Also you asked about debugging.  The fastest and easiest way
is to remove all the #pline from the C source and rebuild and then debug.

I use the following quick hack script to do this:

-- cut here --

#!/bin/sh

for i in *.c
do
        echo $i
        mv $i $i.tmp
        cat $i.tmp | sed "s%^#line%//%" > $i
        rm -f $i.tmp
done

-- cut here --
