#1566 closed Bug (Fixed)

Array as its own element issue

Reported by: trancexx Owned by: trancexx
Milestone: 3.3.9.3 Component: AutoIt
Version: 3.3.6.0 Severity: None
Keywords: Cc:

Description

Code is:

#include <Array.au3>

Global $a[3] = [1, 2, 3]
$a[1] = $a

; And then
$b = $a[1]
$c = $b[1]
$d = $c[1]
$e = $d[1]
$f = $e[1]
;...
_ArrayDisplay($a, "Displaying $a")
_ArrayDisplay($b, "Displaying $b")
_ArrayDisplay($c, "Displaying $c")
_ArrayDisplay($d, "Displaying $d")
_ArrayDisplay($e, "Displaying $e")
_ArrayDisplay($f, "Displaying $f")

If array (old) is put as some element of its own endless* recursion occurs. Expected would be $b to be 1, 2, 3.
Obvious workaround works as expected.

I tried to determine how deep it goes but my RAM was sucked up. 10000 here:

#AutoIt3Wrapper_Run_Au3check=n

	Global $0[3] = [1, 2, 3]
	$0[1] = $0

	$iMax = 10000 ; Probably 16000000 / 3 is the max
	For $i = 1 To $iMax
	Assign($i, Execute("$" & $i - 1 & "[1]"))
	Next
	_ArrayDisplay(Eval($iMax), "Displaying $" & $iMax)

If this is combined with Ticket #1565 AutoIt crashes (stack overflow).

$a = StringSplit("ab", "")
$a[1] = $a

$obj=ObjCreate("Scripting.Dictionary")
MsgBox(64, "", "It will crash now")
$obj.add("test", $a)
