LuaFunction crash on Windows7 64-bit with Mono

[dsblank]

Trying to write a function in C# (to redirect print's output to stdio to a GUI window). Works fine on Linux, but crashing on a Windows7 64-bit computer. (This is my first interaction with LuaSharp and Lua in general, so I might be doing something stupid). I am using the Lua Windows binaries for x86 (the ones made for 64-bit explicitly did not load from LuaSharp.dll).

Test code:

// CSharp code to assign Lua's print function

public static class LuaEnv {

public static void Main() {
LuaSharp.Lua state = new LuaSharp.Lua();
setEnvironment(state);
LuaSharp.LuaFunction p = (LuaSharp.LuaFunction)state["print"];
p.Call(1);
p.Call(2);
p.Call(3);
}

public static void setEnvironment(LuaSharp.Lua state) {
state["print"] = new MyPrint();
}

public class MyPrint : LuaSharp.ClrFunction {

public MyPrint() {
}

protected override object[] OnInvoke(LuaSharp.Lua state, object[] args) {
  System.Console.Write("MyPrint: ");
  System.Console.WriteLine(args[0]);
  return new object[] {null};
}

}
}

Compiled on Linux under Mono 2.6.7 with:

gmcs -target:exe \
    LuaTest.cs \
    -r:LuaSharp \
    -out:LuaTest.exe 

C:\Users\dblank\Desktop\Calico\languages\Lua>mono LuaTest.exe
MyPrint: 1

I've also tried running with later versions of Mono, and it seems to crash after it does the print.

Any ideas appreciated!
