I believe this to be display bug.) You can checkout https://github.com/jwiegley/dot-emacs and then run "make" within the result to approximate what I am doing. > Also, the line numbers you show in the backtrace differ considerably from > what I see in the pretest sources: e.g., move_it_by_lines there starts at > line 8834, and the only place it can call `abort' is on line 8858: > xassert (it->current_x == 0 && it->hpos == 0); This is the one I saw looking up from the abort. > So I'm unable to proceed without either a way to reproduce this crash or > some additional information from you. I hope what I've added helps.

I will do so in future. Thanks, John
