I just did a fresh Ubuntu install, and downloaded TeXmacs 1.99.5, and it crashes right away.

I fetched the image for Ubuntu 16.04 from the ubuntu web site, did the following installation

sudo apt-get install gnome-tweak-tool
sudo apt-get install g++ bison flex ghc

I then remapped my keyboard the way I like it (left-handed mouse, Dvorak keyboard, swap control and caps-lock), and then fetched TeXmacs from the TeXmacs web site, un-tar'ed it, and did this:

davew@davew:~$ PATH=$PATH:/home/davew/TeXmacs-1.99.5-10549M-i386-pc-linux-gnu/bin
davew@davew:~$ export PATH
davew@davew:~$ TEXMACS_PATH=/home/davew/TeXmacs-1.99.5-10549M-i386-pc-linux-gnu
davew@davew:~$ export TEXMACS_PATH

and then started TeXmacs on the command-line, clicked Document->Page... to pop up a second window (page configuration), hit "OK" in that window.

At that point, TeXmacs crashed.

This is on an i7-2600S with 8G of RAM, though I've had this problem on lots of other systems.

Please let me know if this can't be reproduced. I could try it again on the "Try Ubuntu" boot disk, without gnome-tweak-tool, if there's any thought that doing so might have an impact.

If you apply my patch to the texmacs wrapper script, and make sure that the debugging symbols are installed, then you can run it in a terminal or emacs shell buffer, or even under gud with "texmacs --gdb" and it will be launched under gdb. Without the debugging symbols though, it won't give a good result.

I posted the patch in my last bug report on Savannah. I can't access it right now to put a copy into this email because the drive that has my source directory on it is not presently in the caddy; I've got a Windows disk in there so that I can work on upgrading the firmware in my Android tablet today.

I've been telling my students to use Ubuntu and pull the ancient version
of TeXmacs from there. It pre-dates the current issue.

I'll try to generate a crash with a back-trace. It's really with my
1.99.5 install on Ubuntu ... just close one of two windows.
