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:

ObjCreate()
and
GUICtrlCreateObj()
