The problem was when the native offset matched the last debug marker ... now it 
checks for the "==" case as well as ">" case.

Summary:  (new StackFrame(1, true)).GetFileName() sometimes returns null when 
it shouldn't

Original Submission:  Creating a stack frame for the previous method in the 
call stack does not always produce a valid stack frame for that method. The 
GetFileName method sometimes returns null when it shouldn't. It appears to be a 
problem with the offset calculations, because increasing the amount of code in 
the previous method can cause the stack frame for that method to work 
correctly. I've attached a test case which has blocks of code which can be 
defined in to show how the behavior changes. There's a comment at the beginning 
of the test case class explaining what each define does.

P.S. Remember to compile with -g.
