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).
