|
|
|
|
|
// 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. Help to fix all the cases where this is done
