Is there anything fundamentally wrong with this code?

[WhatMeWorry via Digitalmars-d-learn]

The code below compiles fine but I always get a run time abort 
with the error down below.  Isn't the postProc at module scope so 
shouldn't the class instance always be around (ie not 
deallocated?)  If it helps, this was translated from C++ code.  
Thanks.


---------------------file post_processor.d ----------
module post_processor;

class PostProcessor
{
     ...
     GLuint FBO;
     ....
}

---------------------file game.d -------------------
module game;

PostProcessor  postProc; // just a declaration (no memory 
allocation)

class Game
{
     ...
     void initGame(){
         ...
         PostProcessor postProc = new PostProcessor(...);
         ...
     }
     ...
     void update(GLfloat deltaTime){
         ...
         writeln("Right Before");
         writeln("postProcesor.FBO = ", postProc.FBO);
         writeln("Right After);
         ...
     }
     ...
}
