The following code:

CallNonConst()
CallConst()

Func CallNonConst()
	Local $a = 32
	TakesConstByRef($a)
EndFunc

Func CallConst()
	Local Const $a = 32
	TakesConstByRef($a)
EndFunc


Func TakesConstByRef(Const ByRef $c)
	ConsoleWrite($c & @CRLF)
EndFunc

produces this error:

New AutoIt v3 Script.au3(15,37) : ERROR: TakesConstByRef() previously called with expression on Const ByRef param(s).

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^

The error is wrong. The code is perfectly valid. The problem is using a non-const and a const in the same script with the same function. It seems Au3Check is trying to infer something incorrectly. If you modify both examples to be identical (Either add Const to the Local it's missing from or remove it from the one where it's present) then there is no error. All Au3Check needs to worry about is making sure a variable is being passed to the ByRef statement, it doesn't need to concern itself if the variable is Const or not.

Au3Check is not able to recognise Global variables declared inside functions if the variables are used above the function declaration.

Here is an example script which demonstrates this:

CreateVariable()

ConsoleWrite($sGlobalVariable & @CRLF)

Func CreateVariable()
	Global $sGlobalVariable = "Foobar"
EndFunc

Au3Check throws a nasty warning if you run the code above:

Try to run: Track_Au3Check_Main.au3

"Z:\AutoItPortable\__COMUNITY\TRACK\Track_Au3Check_Main.au3"(2,34) : warning: $A: possibly used before declaration.
$A

$A

Z:\AutoItPortable\__COMUNITY\TRACK\Track_Au3Check_Main.au3 - 2 error(s), 1 warning(s)

After quick check you can found out that: the problem is not located in Track_Au3Check_Main.au3 ... but it is inside Track_Au3Check_UDF.au3 as a last line.

Au3Check should show proper line and udf file .
