           Summary: Internal Compiler Error using Declare Function
           Product: Mono: Compilers
           Version: SVN
          Platform: i386
        OS/Version: Ubuntu
            Status: NEW
          Severity: Normal
          Priority: P5 - None
         Component: Basic

It seems that using Declare Function (instead of DllImport) to define an
external function causes the compiler to trip up because a default value
doesn't get set for the charset translation that would normally be specified as
a DLLImport attribute.

The exception comes from the Case Else in the following code, which is from
members/ExternalSubDeclaration.vb line 106:

        Select Case m_CharsetModifier
            Case KS.Auto
               
attrib.AttributeArguments.VariablePropertyInitializerList.Add("CharSet",
System.Runtime.InteropServices.CharSet.Auto)
            Case KS.Unicode
               
attrib.AttributeArguments.VariablePropertyInitializerList.Add("CharSet",
System.Runtime.InteropServices.CharSet.Unicode)
            Case KS.Ansi
               
attrib.AttributeArguments.VariablePropertyInitializerList.Add("CharSet",
System.Runtime.InteropServices.CharSet.Ansi)
            Case Else
                Throw New InternalException
        End Select
