Okay, What's the matter with the attached code then?

I've a C function that looks like this:

   void
   test_params( long level, const char *str, int len )
   {
     printf( "Level: %ld   Str: %p   Level: %d\n", level, str, len );
   }


I export it as:

   [DllImport("libexample")]
   extern public static void test_params( long level, String msg, int len );


Call it like this:

   Goldwater.Native.test_params( level, msg, msg.Length );
   OR
   Goldwater.Native.test_params( 100, "Hello", 5 );


And I get this output:

   Level: 63   Str: (nil)   Level: 135765976


Hmm.
I'm building with the latest tarball (not CVS) release of cscc.


The attached code has a 'build' script to get things working.
This is a simple example extracted from the more complicated wrapper suite 
I'm trying to construct... that one's worse as it core dumps!!


Cheers.
Chris
