FWIW, I use Helix as my main editor and every time it has crashed (probably a few dozen times over a year or two, I've filed issues), it's related to bad text position stuff, where it effectively goes "out of bounds" on the text data structure.
I think its mostly due to multiple buffers showing the same content, as opposed to this Ropey library directly.
That's unexpected. I've used it for over a year and haven't had a single crash. I've used it for data files millions of lines long, and often open the same file in buffers side by side too. Could you share the issue you opened?
