This leads lower than scratch, rather to ground.

Which Scilab version are you using? If < 5.5.0, i guess that this is due 
to this bug:
http://bugzilla.scilab.org/show_bug.cgi?id=10243, that was fixed in 
november 2013.
In this case, upgrading your Scilab should fix the case you met.

Indeed, may be. Many memory leaks were fixed between Scilab 5.4.1 & 5.5.0

Aa! So: upgrade to 5.5.1!
