[Texmacs-dev] TeXmacs-1.0.1.14 + OS X 10.2.6 hangs on session creation

[Gregory Wright]

Hello,

I maintain TeXmacs for the darwinports system under OS X (darwinports 
is similar
to fink but has its roots in the BSD ports system). I've had a problem 
with
recent versions: they hang when creating a session. The problem occurs 
for
a shell, scheme or maxima session (these are the only cases I can test).
The CPU usage becomes very high and TeXmacs is unresponsive.

I've seen this in versions 1.0.1.12 - 14. It doesn't happen in 1.0.1.5, 
the first
version I ported to darwinports.

I've run TeXmacs under gdb, but I'm not certain what it is telling me. 
I've included
a backtrace of the system after it has hung.

I'd be happy to look at this but would appreciate any insights you 
could provide.

The system is TeXmacs-1.0.1.14, Mac OS X 10.2.6, apple X11 beta 3, 
guile 1.6.4.
(The problem also occurs with guile 1.6.3.).

Best Wishes,
Greg Wright
