Thanks. But I'd like to see the report from your normal session, invoked just as you invoke those that crash. > (gdb) p it->current > $3 = { > pos = { > charpos = 1295, > bytepos = 1295 > }, > overlay_string_index = 0, > string_pos = { > charpos = -1, > bytepos = -1 > }, > dpvec_index = -1 > } So this seems to say that there's at least one overlay string at buffer position 1295. Is that reasonable? What was the current buffer when this crashed? You can find that out by typing this at GDB prompt: (gdb) pp current_buffer->name_ (If "pp" doesn't work, type "source /path/to/emacs/src/.gdbinit" and try again.) You can display the relevant part of the text of that buffer like this: (gdb) p current_buffer->text->beg[1200]@100 What does this show? Also, what do the following commands produce?

Thanks, but please also show the above information for the version that did crash.
