This is an insult. I invite you to look at my topmost post and comparte that to your postmortem. It points to the precise position in intervals.c which creates an unexpected behaviour. FYI, I was interested in moving Overlays to Interval trees and add support for Text layers. I am attaching some notes on Overlays that I took, just so that you know I not bull-shitting. Due to various developments on this and related mailing lists, I have put that work on hold. Now, I am positively certain that if I continue to be part of this list and the "other" mailing lists, I only come across as someone who as no self-respect. So Good bye to this list, Jambunathan K.
