107 // really related to the FIX_DOUBLE_SPACE patch. I'd rather think that
108 // this is a problem that has been here almost from day one and that a
109 // larger userbase with differenct access patters triggers the bad
110 // behaviour. (segfaults.) What I think happen is: In several places
111 // we store the paragraph in the current cursor and then moves the
112 // cursor. This movement of the cursor will delete paragraph at the
113 // old position if it is now empty. This will make the temporary
114 // pointer to the old cursor paragraph invalid and dangerous to use.
115 // And is some cases this will trigger a segfault. I have marked some
116 // of the cases where this happens with a warning, but I am sure there
117 // are others in this file and in text2.C. There is also a note in
118 // Delete() that you should read. In Delete I store the paragraph->id
119 // instead of a pointer to the paragraph. I am pretty sure this faulty
120 // use of temporary pointers to paragraphs that might have gotten
121 // invalidated (through a cursor movement) before they are used, are
122 // the cause of the strange crashes we get reported often.
124 // It is very tiresom to change this code, especially when it is as
125 // hard to read as it is. Help to fix all the cases where this is done
126 // would be greately appreciated.
