Jay Berkenbilt a11549a566 Detect loops in /Pages structure ... Pushing inherited objects to pages and getting all pages were both prone to stack overflow infinite loops if there were loops in the Pages dictionary. There is a general weakness in the code in that any part of the code that traverses the Pages structure would be prone to this and would have to implement its own loop detection. A more robust fix may provide some general method for handling the Pages structure, but it's probably not worth doing. Note: addition of *Internal2 private functions was done rather than changing signatures of existing methods to avoid breaking compatibility.		2015-02-21 19:47:11 -05:00
