            Bug ID: 143706
           Summary: Missing Optional argument is not properly missing,
                    when ':=' syntax is used
           Product: LibreOffice
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: BASIC
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: mikekaganski at hotmail.com

Consider this BASIC code:

  ' No Option VBASupport

  Sub Foo(Optional x As Double, Optional y As Double)
    MsgBox ismissing(x) & " " & ismissing(y)
  End Sub

  Sub Bar
    Foo(y:=10)
  End Sub

It produces "False False", instead of expected "True False"; and inspecting
value of x inside Foo gives 0.

In non-VBASupport mode, we should not initialize missing optional arguments;
the problem looks specific to the := argument value syntax, and e.g.

  Foo(, 10)

produces expected "True False".

Tested with Version: 7.2.0.2 (x64) / LibreOffice Community
