Program exited with code 1

[Andrey]

Hello,
I wrote a small test code with WinApi:

----------------------------------------------------
import core.runtime;
import std.utf;

import core.sys.windows.windows;
import core.sys.windows.wingdi;

class Test
{
     public this() nothrow
     {

     }
}

extern(Windows)
int WinMain(HINSTANCE hInstance, HINSTANCE, LPSTR lpCmdLine, int 
nCmdShow)
{
     new Test(); // error is here
     return 0;
}
----------------------------------------------------

When I run it, there is an error: Program exited with code 1.

If I comment "new Test();" - no error happens. Why? How to create 
instances of classes?
