138 // this is a problem that has been here almost from day one and that a
139 // larger userbase with differenct access patters triggers the bad
140 // behaviour. (segfaults.) What I think happen is: In several places
141 // we store the paragraph in the current cursor and then moves the
142 // cursor. This movement of the cursor will delete paragraph at the
143 // old position if it is now empty. This will make the temporary
144 // pointer to the old cursor paragraph invalid and dangerous to use.
145 // And is some cases this will trigger a segfault. I have marked some
146 // of the cases where this happens with a warning, but I am sure there
147 // are others in this file and in text2.C. There is also a note in
148 // Delete() that you should read. In Delete I store the paragraph->id
149 // instead of a pointer to the paragraph. I am pretty sure this faulty
150 // use of temporary pointers to paragraphs that might have gotten
151 // invalidated (through a cursor movement) before they are used, are
152 // the cause of the strange crashes we get reported often.
154 // It is very tiresom to change this code, especially when it is as
155 // hard to read as it is. Help to fix all the cases where this is done
