AutoIt HardCrash with ObjCreate and GUICtrlCreateObj

[mLipok]

I found a nice script here:
​http://www.autoitscript.com/forum/topic/141103-barcode-udf/page-2#entry1117722

I was trying to use it and I had HardCrash.

It happen on production and latest beta AutoIt

you can get ActiveX: OcvitaBarcode.ocx here:

exactly :

Here is my smalest reproduction script with comment:

Global $oBCode, $oBCodeGUI


$GUI = GUICreate("OCVITA_BARCODE by AutoIt3, Valery Ivanov, 19 September, 2013", 400, 400, -1, -1)
$oBCode = ObjCreate("Ocvita.Barcode")
$oBCode.symbology = 1
$oBCodeGUI = GUICtrlCreateObj($oBCode, 10, 110, 380, 280)
GUISetState()

ConsoleWrite('!' & @ScriptLineNumber & @CRLF)
; check - if step 1 is OK
$oBCode.AboutBox()

ConsoleWrite('!' & @ScriptLineNumber & @CRLF)
CRASH_IS_HERE_RefreshBCode(2)

; check - if step 2 is OK
$oBCode.AboutBox()

Func CRASH_IS_HERE_RefreshBCode($NewSymIndex)

	; Crash only if this ObjCreate is used - comment them to avoid crash
	$oBCode = ObjCreate("Ocvita.Barcode")
	ConsoleWrite('!' & @ScriptLineNumber & @CRLF)
	$oBCode.symbology = $NewSymIndex
	ConsoleWrite('!' & @ScriptLineNumber & @CRLF)

	; !!!!!!!!! EXACTLY HERE
	$oBCodeGUI = GUICtrlCreateObj($oBCode, 10, 110, 380, 280)
	ConsoleWrite('!' & @ScriptLineNumber & @CRLF)
EndFunc   ;==>CRASH_IS_HERE_RefreshBCode

And I want to ask:
if you can add some @error chcecking to:
ObjCreate()
and
GUICtrlCreateObj()

On my Win7 SP1 64bit AutoIt 3.3.13.12
this your script DOESN'T crash.
It runs without any errors.

Replying to Zedna:

On my Win7 SP1 64bit AutoIt 3.3.13.12
this your script DOESN'T crash.
It runs without any errors.

it works without crash but only when I comment the second one :

$oBCode = ObjCreate("Ocvita.Barcode")

I do test on other systems.

[mLipok]

Please close this ticket.
It works on other systems only crash on my own.
I'll open new thread in forum.
When I find an answer why this script crash then maybe I will back to this track ticket, or open new.
