The code inserted the new entry after the cursor, but before the real end of the ellipsis: [cursor] ... element_t <-> element_t <-> element_t <-> element_t "<U0000>" "<U0001>" "<U007F>" startp endp At the end of the function we have: [cursor] ... element_t <-> element_t <-> element_t "<U007E>" "<U007F>" endp The cursor should be pointing at endp, the last element in the doubly-linked list, otherwise when execution returns to the caller we will start inserting the next line after <U007E>. Subsequent operations end up unlinking the ellipsis end entry or just leaving it in the list dangling from the end. This kind of dangling is immediately visible in C.UTF-8 with the following sorting from strcoll: <U0010FFFF> <U0000FFFF> <U000007FF> <U0000007F> With the cursor correctly adjusted the end entry is correctly given the right location and thus the right weight. Retested and no regressions on x86_64 and i686. Co-authored-by: Carlos O'Donell <carlos@redhat.com> -- You are receiving this mail because: You are on the CC list for the bug.
