[Mono-list] Bug in the interpreter: pinvoke

[Adam Treat]

I've come across a bug in the interpreter when using DllImport.  You can not 
pass two strings as arguments to a DllImport statement.  If you do it balks 
and throws a 'NullReference null was found where object was required' 
exception.  The jit works fine with this.  This was found running on linux. 
Example:

[DllImport("libsomelib.so", EntryPoint="someentrypoint")]
public static extern int new_Test(string test1, string test2;

public static void new_Test(string test1, string test2) {

}

I know the interpreter and jit share code for PInvoke, so don't know exactly 
what's happening.
