Steps to Reproduce Behavior

A crash will occur when compiling to native code in either of the following two scenarios:

Scenario 1:

1. Start Visual Basic 5.0 and create a new Standard EXE. This creates a

   form named Form1 by default as part of a project named Project1 by
   default.

2. From the General Declarations area of Form1, add the following code:

      Sub MySub(arvArray1 as variant)
          Dim arvArray2() as variant
          arvArray2(1,1) = arvArray1()
      End Sub

3. From the Project menu, select Project1 Properties. In the Project

   Properties dialog, select Compile to Native Code on the Compile tab.

4. Click OK.

5. From the File menu, select Make Project1.exe. This will produce an

   application error in VB5.exe.

Scenario 2:

1. Start Visual Basic 5.0 and create a new Standard EXE. This creates a

   form named Form1 by default as part of a project named Project1 by
   default. Add a class module to this project by clicking on Add Class
   Module from the Project menu.

2. In the General Declarations area of the Class module, add the following

   code:

      Public Property Get MyProp( _
           arvArray1 As Variant) As Variant
           Dim arvArray2() As Variant
           arvArray2(1, 1) = arvArray1()
      End Property

3. From the Project menu, select Project1 Properties. In the Project

   Properties dialog select Compile to Native Code on the Compile tab.

4. Click OK.

5. From the File menu. select Make Project1.exe. This will produce an

   application error in Visual Basic 5.0.
