What I think happen is: In several places // we store the paragraph in the current cursor and then moves the // cursor. This movement of the cursor will delete paragraph at the // old position if it is now empty. This will make the temporary // pointer to the old cursor paragraph invalid and dangerous to use. // And is some cases this will trigger a segfault. I have marked some // of the cases where this happens with a warning, but I am sure there // are others in this file and in text2.C. There is also a note in // Delete() that you should read. In Delete I store the paragraph->id // instead of a pointer to the paragraph. I am pretty sure this faulty // use of temporary pointers to paragraphs that might have gotten // invalidated (through a cursor movement) before they are used, are // the cause of the strange crashes we get reported often. // // It is very tiresom to change this code, especially when it is as // hard to read as it is.
