Hi Lonkero,
I've created a simpler recursive function that produces a count.
 Code:
break on
$ = setoption("wrapateol","on")
recurs(1)
?
return
function recurs($i)
If $i<100000
   $i "  "
   recurs($i+1)
endif
endfunction

Kix 464 bombs out at 2116 whilst 453 bombs at 8356.
So this older version seems to have 4 times more stack space.
460, 461 both bomb out at 23768
462, 463 at 2169
So I think versions 460 and 461 had a lot more going for them.

Cheers,
