Fixed in CVS 29th May 2004 (didn't make it into 0.6.6)

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

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.
