[Debian-science-sagemath] Doctests failing with "ECL says: THROW: The catch MACSYMA-QUIT is undefined."

[Tobias Hansen]

Hi,

after updating our package to sage 7.4 the doctests are failing with
errors like [1] (see end of message).

sage/interfaces/maxima_lib.py, line 177 is this:

for l in init_code:
    ecl_eval("#$%s$"%l)

where

init_code = ['besselexpand : true', 'display2d : false', 'domain :
complex', 'keepfloat : true',
            'load(to_poly_solve)', 'load(simplify_sum)',
            'load(abs_integrate)', 'load(diag)', 'nolabels : true']

The errors can be reproduced by running in ecl:

(require 'maxima "/usr/lib/ecl/maxima.fas");
(in-package :maxima);
#$load(to_poly_solve)$;

which gives:

append: argument must be a non-atomic expression; found false
 -- an error. To debug this try: debugmode(true);

Condition of type: SIMPLE-CONTROL-ERROR
THROW: The catch MAXIMA::MACSYMA-QUIT is undefined.
Available restarts:

I'm not sure if this is expected to happen here, since sage runs other
commands before to set maxima-in-ecl up properly. However the error
message does not tell me anything and I have no idea what the problem
is. I also could not find any ecl or maxima related changes between sage
7.3 and 7.4 that seemed relevant.

Does someone have an idea?

Best,
Tobias
