The latest TeXmacs from CVS segfaults immediately on a very simple
example. This makes it pretty useless for me ATM :-(. I've attached
the *.tm file and the gdb backtrace. How can I investigate this
further? (I'm running on Linux.)

The `.' character in the axiom* environment is necessary to produce
the segfault: without it TeXmacs shows the page OK.

Regards,
