[Mono-dev] __arglist and P/Invoke

Mono isn't able to handle __arglist in a P/Invoke signature. For example, the following program (which calls 'printf' of the the standard C library) is working fine with MS.NET.

using System.Runtime.InteropServices;

class Program
    public static extern void printf(string format, __arglist);

    static void Main()
        printf("number %d\n", __arglist(10));

If I try to use Mono, I encounter two problems:

1) The Mono C# compiler doesn't add 'vararg' to the method definition for printf.
2) If I try to execute the sample (compiled with MS.NET's C# compiler) a internal exception is thrown:

Unhandled Exception: System.InvalidProgramException: Invalid IL code in Program: Main (): IL_0008: call      0x0a000011

Are these problems likely to be fixed in a future version of Mono ?
