[Texmacs-dev] texmacs 1.99.3 crashes on export to PDF

[Kostas Oikonomou]

Hi, I've been having a problem with the SVN versions of texmacs on
FreeBSD 10.  TeXmacs always crashes (segmentation fault) on trying to
export anything to PDF.  E.g. the "Welcome" document under the  Help menu.
This happens even with the latest SVN, 1.99.3:

address@hidden ~]$ /opt/texmacs/svn-qt/bin/texmacs
TeXmacs] With linked TrueType support
Reading ko-kbd.scm...
Throwing segmentation fault

Is it possible to debug this using the Debugging tool?  Is there any
information on how the debugging tool is supposed to be used? 

Thanks.
