Possible Maps Bug (Beta)

[qsek]

Can somebody try to reproduce this bug?

It would be helpful to know if this issue appeares on other environments too.

Issue:

Sometimes values of certain keys will return empty even if expicitly assigned a value before.

Conditions:

• Map is bigger than ~50 key/values pairs
• value is being worked with in a Function where a loop is iterating through the Map
• before retrieving the value there is a isMap/MapKeys/MapAppend/MapRemove check on the Map value.

Dim $mMap[]

; Generate random key strings
For $i = 0 To 100
    $RndKey = ""
    For $i2 = 0 To 4
        $RndKey &= Chr(Random(65,90,1))
    Next
    $mMap[$RndKey] = 999
next


ConsoleWrite("-----------1-------------" & @CRLF); Unpredictable blank values

MapDisplay1($mMap)

ConsoleWrite("-----------2-------------" & @CRLF); ByRef always works

MapDisplay2($mMap)

ConsoleWrite("-----------3-------------" & @CRLF); not in a function always works

For $i In MapKeys($mMap)
    isMap($mMap[$i])
    ConsoleWrite($i&": "&$mMap[$i]&@CRLF)
Next


Func MapDisplay1( $m_Map )
    For $i In MapKeys($m_Map)
        isMap($m_Map[$i]) ;same problem with isMap($m_Map[$i]), MapKeys($m_Map[$i]), MapAppend/MapRemove but NOT with MapExists($m_Map,$i)
        ConsoleWrite($i&": "&$m_Map[$i]&@CRLF)
    Next
EndFunc

Func MapDisplay2( ByRef $m_Map ) 
    For $i In MapKeys($m_Map)
        isMap($m_Map[$i])
        ConsoleWrite($i&": "&$m_Map[$i]&@CRLF)
    Next
EndFunc

 

The value is not lost or overwritten on the global map, only on the local map inside the function.

Ack, it's very strange. File a bug in tracker.
