SetError fails if a function is called before returning

[TheDcoder <TheDcoder@…>]

Hello! I have discovered another somewhat frustrating bug. SetError fails if a function is called before returning. Here is an example:

#include <MsgBoxConstants.au3>

Example()

If @error Then
	ConsoleWrite("Error" & @CRLF)
Else
	ConsoleWrite("No Error" & @CRLF)
EndIf

Func Example()
	SetError(1)
	Sleep(1000)
EndFunc

Expected output is Error but the actual output is No Error which should be wrong as we have called SetError(1). If Sleep(1000) is removed then it works, this concludes that any error set using SetError will be erase if a function is called before returning!

Here is some more proof that the bug only occurs when using statements which call a function:

#include <MsgBoxConstants.au3>

Example()

If @error Then
	ConsoleWrite("Error" & @CRLF)
Else
	ConsoleWrite("No Error" & @CRLF)
EndIf

Func Example()
	SetError(1)
	Local $iNumber = @SEC
	If $iNumber * 1000 <= 1000 Then $iNumber = 0
EndFunc

This snippet will output Error as expected.

No bug. @error is being reset by the Sleep function as explained in the Help file:

When entering a function @error is set to 0

Ah! Thanks for pointing that out M23, sorry for not reading the remarks in the help file. The behaviour is different from what I thought... I am curious so I will start a topic about it at the forum :)
