In the present version (1.0.7.15), maxima's interactive questions are correctly handled. Therefore I close this bug.

The following information has been sent by
Emmanuel Charpentier <charpent@bacbuc.dyndns.org> :

I think I have another instance of the same bug.

Let's try to check that the sum of two normally distributed variables is
also normal (basic probs) :

In xmaxima (see enclosed file, the output us too wide not to be mangled
by mailer's reformatting), I get (almost) what I want (need to further
factorize the exponent, but the result is there. Marvelous, if you're
old enough to remember sweating blood and tears to derive this by hand
...). You note that assuming that standard errors are positive allows
maxima to answer directly. Forgetting the assumption forces maxima to
prompt for the signs of the standard errors.

In a maxima session in TeXmacs, I get the same result, up to the point I
cancel the "positive s. e." assumption. When I re-ask for
bar[x,mu[1],sigma[1],mu[2],sigma[2]), TeXmacs segfaults.

Furthermore, when relaunching TeXmacs, I can either accept the
restoration of the autosave file, or find myself with a stubbornly
locked TeXmacs, that accepts only an exit command.

Hope this helps pinpointing the problem,

Emmanuel Charpentier

While 1.0.4-R3 still hangs on the qustion posed by maxima,
texmacs 1.0.4.3 now crashes with segmentation violation.

Karl Hegbloom <karlheg@cs.pdx.edu> submitted the followin bug:

The input: integrate((4+u^2)/(u^3),u,1,2)

.... will, with Maxima running in a terminal, prompt with:

Is PLOG(- u) + 2 an odd number?

.... but the Maxima interface in TeXmacs does not notice, and appears to hang at that point.
