Thanks for confirming this, Sven.
function void simple (const int N[2::])

would put a const in front of an int ;-)
It also does not crash in case the lower bound is _not_ hit <function
void simple (const int N[1::])> ;-)
That is true. Writing const is such an automatism for me ;-) Even though
the pointer speed effect is negligible in this case, I still have the
"security effect" that the supposed to be constant parameter cannot be
overwritten ;-)
Actually, I believe it is not supported by hansl to do "const int": The
guide says "the const modifier may be used... for all the types that
support the pointer apparatus". And if you try the following function:
<hansl>
function void simplestar ( int *N)
print "very simple"
end function
</hansl>
you get the error message "unknown data type 'int *'". You have to use
"scalar *N" instead. And indeed, the variant "const scalar N[2::])"
works and doesn't crash.
Yes, that sounds familiar to me.
But of course the above is a bad bug anyway, and "const int" should be
intercepted by gretl in the first place.
Or may be not so given the other side effect I mentioned: the "security
effect" ;-)
