[Jeremy Henty <address@hidden>]

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, 

Jeremy Henty
