At least, the crash no longer occurs.<br/>
However, when we try to compare a complex to a real like with
2<%i, an error should be yielded instead of returning %F.
Otherwise, the complementary comparison 2>=%i could be
interpreted as %T, what is definitely not the case.<br/>
So: when such a comparison is done, we may test the existence of
%s_1_s_custom() , that may be defined in an external way (%s_1_s()
being already defined in Scilab).<br/>
* If it exists: we call it<br/>
* otherwise, we yield an error with a message inviting the user to
define %s_1_s_custom()<br/><br/>
I will propose a commit in this way, on the 6.0 branch.<br/><br/>
