Dear TeXmacs community:

   Since the last update of my Gentoo-Linux system I cannot launch any
session inside TeXmacs, but scheme sessions. I think this is not a
TeXmacs issue because version 1.99.16 worked fine with sessions,
but not anymore. The same happens with versions 1.99.17 and 1.99.18.
I've also tried to recompile guile, with no success.

   For instance, launching "tm_maxima 5.44.0 sbcl" from bash works.
But "(make-session "maxima" "default")" from a scheme session, causes
segmentation fault as well.

   Somebody has a clue of the problem? Any help is very appreciated.
Best regards.

Pablo
