_Singleton crash on x64 with flag 2

[archrival]

The simple script below causes an app crash. Should this be supported or am I missing something obvious?

#include <Misc.au3>
#AutoIt3Wrapper_UseX64=y
If _Singleton("Global\testapp", 2) = 0 Then
Exit
EndIf

FYI, I've determined it is this call:

Local $aRet = DllCall("advapi32.dll", "bool", "InitializeSecurityDescriptor", _
"ptr", $pSecurityDescriptor, "dword", $SECURITY_DESCRIPTOR_REVISION)

It's a bug. Will be fixed.

Thanks.

Is it a bug in the UDF or the AutoIt code? If it is in the UDF I'd love to know what the fix is.

Ditto here.. having saving issue and would love to either hotfix it myself in the UDF. If its not in the UDF, then at least know when it is expected to be fixed in a release.

Thanks!

The bug was inside UDF. This was wrong:

; The size of SECURITY_DESCRIPTOR is 20 bytes.  We just
; need a block of memory the right size, we aren't going to
; access any members directly so it's not important what
; the members are, just that the total size is correct.
Local $tSecurityDescriptor = DllStructCreate("dword[5]")

It should be:

Local $tSecurityDescriptor = DllStructCreate("byte;byte;word;ptr[4]")

That's all.

That works. Thank you.
