[Mono-dev] Not sure if this is a bug or my env

I just acquired a new mac notebook this week, and tried creating a simple app as shown below in test.cs - which i am just doing in a hurry to test my mono built from mono-master (latest, if i did it right)…

It crashes immediately on run..  

If I run it against mono 2.10.9 it just seems to freeze and not create a window but not crash or exit either...

Is it likely that something is wrong with my environment, or is this a bug?  Or is it just bad code that i slopped together in a hurry causing this?

I know i did a patch about 4 months ago that affected XPlatUICarbon, but i think that patch was reverted, so i don't think i broke this if it is indeed broken, it doesn't look like the area of code that i was touching back then.

@ cat test.cs
using System.Windows.Forms;

class test {

	public static void Main() {	
		Form fm1 = new Form();
		TextBox Tb1 = new TextBox();
		Tb1.Location = new System.Drawing.Point(10,10);
		Tb1.Size=new System.Drawing.Size(80,20);
