I decided to use xfig to produce a nice drawing for my project
and then dump it to postscript so I could send it some co-workers
at remote sites.  I had no trouble drawing the figure, but when I
got around to dumping it to a postscript file, it kept producing
a zero length file.  I finally noticed that it was issuing the
following error message:

  Usage: f2ps [-f font][-s size][-e scale][-N][-c] [input [output]]

It seemed odd to me that xfig wouldn't know how to issue a well-formed
f2ps command, but I persevered by next asking it to just send the
figure directly to the printer.  It responded with:

  lpr: standard input: empty input file

I wondered if it was even producing correct fig output, so I saved
the figure to a .fig file and exited and entered xfig a few times,
reading and writing the figure from/to the .fig file each time.
Xfig at least had no problem reading its own output.

Finally, I decided to run the .fig file through f2ps myself, to
which f2ps provided the following rather rude response:

  > f2ps ~/lib.fig
  atan2: DOMAIN error
  atan2: DOMAIN error
  atan2: DOMAIN error
  atan2: DOMAIN error
  Segmentation fault (core dumped)

Have any of you folks seen this kind of behavior out of xfig/f2ps?
If so, do you have any idea what might be wrong and how I can fix
it?  Replies via e-mail, only, please.

Thanks very much for any help you can provide.
