            Bug ID: 126014
           Summary: Crash on & opening recovered file after removing title
                    from long(?) Table Of Contents [EDITING] [FILEOPEN]
           Product: LibreOffice
           Version: 6.2.4.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: gamemanj at hotmail.co.uk

Description:
LibreOffice crashes after removing title from a long Table Of Contents in the
file referenced in the reproduction steps.
The resulting file on recovery also crashes.
I'm not sure of the details.

Steps to Reproduce:
1. Open https://20kdc.duckdns.org/Crasher.odt
2. Edit the Table Of Contents index
3. Remove the text from the index's title
4. Confirm - Program will crash.

Actual Results:
Program will crash.
Recovered file should be similar to https://20kdc.duckdns.org/Crasher.odt_0.odt
and this will crash the program too.


Expected Results:
Removal of title from Table Of Contents.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
Text contents of file were changed before reporting, but I confirmed the new
file does still have the same effect.
It seems reduction of the size *too much* causes the crash not to happen - if
it doesn't happen, maybe copy/paste some chapters, IDK?

UserProfile reset was performed as going into safe mode, rather than a true
reset - this should be sufficient?

I am assuming that "Use hardware acceleration" means OpenGL is on because the
option you specify on the "checking" page doesn't exist.

Version: 6.2.4.2.0+
Build ID: 6.2.4-1
CPU threads: 8; OS: Linux 5.1; UI render: default; VCL: gtk3; 
Locale: en-US (en_US.UTF-8); UI-Language: en-US
Calc: threaded

Arch Linux package in use:
extra/libreoffice-fresh 6.2.4-1 [installed]
    LibreOffice branch which contains new features and program enhancements

Backtrace (for a 'opened corrupted file' run):
https://20kdc.duckdns.org/crasher-gdbtrace.log

Valgrind seems to slow things down a *lot* - ask if you can't recreate it
