Thanks Samuel, I didn't know this function. So I face a problem (a bug?):
Scilab cratches with segfault but without reaching the recursionlimit. Here the
used three functions
function out=test_l(in)
if in==0 then
out=in;
return
end
out=in+test_l(in-1);
endfunction
function out=test_ll(in,acc)
if in<=1
out=acc;
return
end
out=test_ll(in-1,acc+in);
endfunction
function l_test(in)
i=1;
while 1
mprintf("\n%d: ",i)
sleep(.5,"s");
select in
case 1
out=test_l(i);
case 2
out=test_ll(i,1);
end
mprintf("%d\n",out)
i=i+1;
end
endfunction
There is no problem with
> recursionlimit(20)
> l_test(1)
The program stops as expected with the message "Limite de récursion atteinte
(20)" when i=19 and
> recursionlimit(20)
> l_test(2)
stops when i=20 (I was wrong when I talked about tail call in my previous
email!). But, with
> recursionlimit(1000)
> l_test(1)
Scilab cratches at i=41 with segfault and with
> recursionlimit(1000)
> l_test(2)
Scilab cratches at i=140. Is this cratch a know bug? (It's quite far from the
recursion limit!)
(Subsidiary question: while l_test(2) stop 1 iteration after l_test(1) with low
recursion limit, l_test(2) allows around 100 iterations more than l_test(1)
before cratch with recursionlimit(1000)! Where does it comes from?)
