Hello list(s),

Those of you wishing to use recent versions of Octave within TeXmacs
have probably encountered the fatal errors described in bug #20312 [1]
(Debian bug #424877 [2]). A patch has recently been submitted upstream
[3]. You can apply it directly to the SVN source, or wait (perhaps
another 2.5 years?) for the bug to be fixed in future releases.

In the meantime, you can simply apply the patch attached, as follows:
  # patch -p0 < octave3.patch

Only scripts are affected, so no compiling is needed. Tested with
TeXmacs version 1.0.7.2 and Octave version 3.0.5.

Hope this helps.
