This particular bug was in my 'archiver' code.
It might be that other synchronization problems
relative to the Qt port persist, although they
tend to become rare now.

Occasionally, some very nasty segfaults occur due to
synchronization errors, which are hard to reproduce.
It might be that they only occur inside CAS sessions.
One more or less reliable way to reproduce the bug
(a few tries may be necessary) goes as follows:

1) Open TeXmacs
2) Start a scheme session
3) Execute some incorrect input, e.g. "(define (f x) (+ x x"
4) Go up and execute the corrected input "(define (f x) (+ x x))"
5) Go up

The error should produce itself when going up.
The backtace differs from one run to another,
which makes me suspect a synchronization error.
You may wish to enter and execute one more input line,
such as "(f 3)", in order to increase the likeliness that
the bug will occur. The bug always occurs when moving
the cursor up to a previous input.
