An XLSM with a VBA macro showing infinite recursion in LibreOffice Basic

Running 'main' macro from the attachment produces this error:

> BASIC runtime error.
> '28'
> Not enough stack memory.

It runs OK in Excel, showing a message box with "1".

The macro code there is this:

Option VBASupport 1
Function NotRecursive()
  Set NotRecursive = New Collection
  NotRecursive.Add "Foo"
End Function

Sub main()
  Dim c
  Set c = NotRecursive
  MsgBox c.Count
End Sub

The infinite recursion happens on 'NotRecursive.Add "Foo"', where LibreOffice Basic tries to call the function again.

Possibly this should only be fixed in VBASupport mode.
