Hi all,
Upon quitting Sage, Maxima may keep running and eat up all memory (gasp!).
I just created ticket #13831 for this, with the following content:
How to reproduce: In a clean directory, put the following makefile:
truc:
/opt/sage-5.2/sage crash-maxima.sage
(editing the location of sage to your local setup)
In a file crash-maxima.sage, put:
x, y = var('x y')
desolve_rk4(x*y*(2-y), y, ics=[0,1], end_points=[0, 1], step=0.5)
then type:
make truc
I did not manage to reduce this further, and in particular to
reproduce the issue without going through make. I tried the obvious
things like checking what had changed in the environment and which
shell was used to run the make recipe.
This is on Ubuntu 11.10, with Sage 5.3, 5.4, 5.4.1, and 5.5.rc0. With
Sage 5.3 the memory seems to be eaten up at a faster speed. A few
colleagues got the same crash on slightly different platforms (it
appeared in our build process for the book Calcul Mathématique avec
Sage).
Cheers,
Nicolas
