Subject: xfig 3.2-5c crashes with dash-dotted lines on cygwin
From: Jessica Purcell <jessica DOT purcell AT gmail DOT com>
To: cygwin AT cygwin DOT com
Content-Type: text/plain; charset=UTF-8

When I attempt to create or read in an object with line_style
dash-dotted, xfig crashes with the following message:

xfig3.2.5c: SIGSEGV signal trapped
xfig: attempting to save figure
xfig: 1 object(s) saved in ".../SAVE.fig"

[1]    Abort                         xfig -specialtext -latexfonts
-startlatexFont default (core dumped)


Here is how I got the crash:
1. Start xfig.
2. Select polyline.
3. Select line_style dash-dotted (internal code 3)
4. Draw polyline.
Xfig crashes.

Similarly, if I try to open a .fig file containing an object with
line_style dash-dotted, xfig crashes with a similar message:

xfig3.2.5c: SIGSEGV signal trapped
xfig: Figure is empty or not modified - exiting without saving.

[1]    Abort                         xfig -specialtext -latexfonts
-startlatexFont default SAVE.fig (core dumped)


Creating and reading in files using solid (code 0), dashed (code 1),
or dotted (code 2) lines causes no problems. Dash-dot-dot and
dash-dot-dot-dot (codes 4 and 5) also cause a crash.

After doing a little searching for this error, I found nothing on the
cygwin site. I did find some discussion of (what sounds like) the same
error on a couple of linux sites, from 2014:

http://lists.opensuse.org/opensuse-updates/2014-02/msg00049.html
http://lists.opensuse.org/opensuse-bugs/2014-01/msg02798.html
https://bugzilla.redhat.com/show_bug.cgi?id=1023744

A proposed fix for ubuntu:
http://rlog.rgtti.com/2014/06/26/quick-fix-xfig-bug/comment-page-1/

I did try reinstalling xfig on cygwin, to make sure I had the most
current version, in case this bug had been fixed, since this seems to
be a known error. Then I repeated the steps above. Xfig still crashed.

Any way for me to get a version of xfig on cygwin with this bug fixed?
