Steps to Reproduce Behavior

Create a new ActiveX DLL project (Project1). Class1 is created by default.
Paste the following code in the General Declarations section of Class1:
```
      Public Function Test(a,b)
         Test = 3
      End Function
                        
```
NOTE: The exact function is not important. This error may also occur with Property Let and Property Get statements.
Change the Instancing property of Class1 to 6 - GlobalMultiUse.
Save Project1.
Go to File | Add Project to add a Standard EXE (Project2) to the project group.
From Project2, go to Project | References, to reference Project1 by clicking on its check box.
In the Form_Load event procedure of Form1, type Project1.test, and then hit the space key. An application error should occur.
