Bug#777473: Crash on big computation

[Julien Puydt]

Package: ecl
Version: 13.5.1+dfsg2-4.2

In sagemath's ecl, the following code works (it's real slow, of course) 
-- while it fails quite fast with the debian package, and even kills the 
interpreter:
(ext:set-limit 'ext:heap-size 0)
(setq a (expt 10 (expt 10 5)))
(setq b (expt a 600))

Duplicate large block deallocation

The goal of that code in sagemath is to check that they have a big 
heapsize (that's why they set the limit to zero).

Thanks,
