Notes:

1.  count and marker are both volatile
2.  I can get it to break with the following, as well.

	if(count >250){
			
			marker = 0;  [Breakpoint Here]

			count = 3;
			}

It's almost like I need to have something set to zero before the
breakpoint is triggered within an if statement.

4. I get breakpoints normally when I'm not in an if statement
