it is a strange problem I have : using either debian's ecl or upstream's the following code :(ext:set-limit 'ext:heap-size 0) (setq a (expt 10 (expt 10 5))) (setq b (expt a 600)) gives a crash (SIGABRT) "Duplicate large block deallocation". Where things get interesting, is that I get this code from sage, where it actually works! What is annoying is that the last line comes from this test (src/sage/interfaces/maxima.py, around line 570) : Test that we can use more than 256MB RAM (see trac :trac:`6722`):: sage: a = maxima(10)^(10^5) sage: b = a^600 # long time -- about 10-15 seconds but trac's ticket #6722 is about spellchecking some modules... so I guess there used to be a problem like the one I have, but I don't know what was done to fix it. Does someone remember ?
Upstream acknowledged it is a bug, still present in the devel version. I'll try to help them pinpoint and fix the problem -- if someone here has a clue why it works in sage, I'm sure they would appreciate the information.
