            Bug ID: 124569
           Summary: Undoing a deletion of text with fieldmarks moves the
                    closing fieldmark 2 chars right
           Product: LibreOffice
           Version: 4.2.1.1 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: phil.krylov at gmail.com

Description:
Undoing a deletion of text with fieldmarks moves the closing fieldmark 2 chars
right. Further redo/undo actions cause more destruction.

Steps to Reproduce:
1. Here (see attachment) is a simple document containing a fieldmark pair
(generated using the script from bug 116960). The fieldmarks are between ||
vertical line characters. Select everything between | characters (inclusively,
to be sure you also select both invisible fieldmark characters).
2. Press Del.
3. Press Undo.

Actual Results:
The closing fieldmark (and the shading) has moved 2 characters right, including
the gray shading. [To have more fun: Press Redo. More text is deleted than the
first time. Press Undo again. Different things can happen depending on your
version. An assertion crash, removal of the first fieldmark etc.]

Expected Results:
Proper undo of fieldmark deletion.


Reproducible: Always


User Profile Reset: No



Additional Info:
The earliest version where the bug can be reproduced exactly is 4.2.1.1. In
4.2.0.4, I can't select anything, 4.2.0.3 Mac download is missing, 4.1.6.2 and
4.2.0.2 do not let you delete fieldmarks, 3.6.7.2 seems to work properly.
