47 // This is the comments that some of the warnings below refers to.
48 // There are some issues in this file and I don't think they are
49 // really related to the FIX_DOUBLE_SPACE patch. I'd rather think that
50 // this is a problem that has been here almost from day one and that a
51 // larger userbase with differenct access patters triggers the bad
52 // behaviour. (segfaults.) What I think happen is: In several places
53 // we store the paragraph in the current cursor and then moves the
54 // cursor. This movement of the cursor will delete paragraph at the
55 // old position if it is now empty. This will make the temporary
56 // pointer to the old cursor paragraph invalid and dangerous to use.
57 // And is some cases this will trigger a segfault. I have marked some
58 // of the cases where this happens with a warning, but I am sure there
59 // are others in this file and in text2.C. There is also a note in
60 // Delete() that you should read. In Delete I store the paragraph->id
61 // instead of a pointer to the paragraph. I am pretty sure this faulty
62 // use of temporary pointers to paragraphs that might have gotten
63 // invalidated (through a cursor movement) before they are used, are
64 // the cause of the strange crashes we get reported often.
66 // It is very tiresom to change this code, especially when it is as
67 // hard to read as it is. Help to fix all the cases where this is done
68 // would be greately appreciated.
