Comment 12 Jerry James 2014-05-07 16:35:30 UTC 
Thanks for the report, Jan.  This looks like infinite recursion while trying to print a recursive structure, namely a vector that contains at least one function that contains a pointer back to the same vector.  If you created the recursive structure on purpose, then you need to bind print-circle to t before printing.  If you did not create it on purpose, can you tell me what you did that triggered the crash?
Comment 13 jan p. springer 2014-05-08 07:01:44 UTC 
nothing unusual, just opened a latex file. opening any other file works, but loading a latex file crashes xemacs. i've also tried to starting xemacs w/ -q and -vanilla, but that still crashes if loading a latex file.
Comment 14 Jerry James 2014-05-08 13:48:03 UTC 
Aha.  Now I can reproduce the crash.  Thanks, Jan, I will look into how to fix this.
Comment 15 Jerry James 2014-05-08 15:53:40 UTC 
This crash is specific to the XFT build.  The non-XFT build should be usable for opening LaTeX files.  Still trying to figure out how to fix the XFT build...
Comment 16 jan p. springer 2014-06-02 14:01:07 UTC 
just wanted to see if there's any progress on this?
Comment 17 Jerry James 2014-06-02 15:12:43 UTC 
Yes, the crash (actually 2 separate bugs working together) has been identified and fixed upstream.  A new upstream release is in the works.  As soon as that comes out, I will build it for Fedora.

If it appears that the new release will take awhile, I will attempt to backport the bug fixes.  I will talk to the release manager to see what his estimated time to release is.
