simple vb6 chr0 comparison project

I've found a BIG problem in VB6 string (BSTR) comparison.

The VB6 program perform this very simple check. In Windows s is different from
chr$(0) (null char) but in wine NOT!

s = ""
  If s = Chr$(0) Then MsgBox "ERROR, MUST NOT BE EQUAL!!!" Else MsgBox "OK!"

[see attachment]

This is a major bug, since chr$(0) is used in many ways in vb6 (and also in
API)

I've tried this simple program in Wine 0.9.49 and wine 1.1.2 with the same
result.
I think this bug should be fixed for wine 1.2!
