            Bug ID: 140590
           Summary: Crash in: mergedlo.dll:  Using Save-As dialog in
                    Tools>Chapter Numbering 28 times gave a crash
           Product: LibreOffice
           Version: 7.2.0.0.alpha0+ Master
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer

This bug was filed from the crash reporting server and is
br-f1f45f5c-7d4d-4c0d-995f-23367215a550.  Reason: 
EXCEPTION_ACCESS_VIOLATION_WRITE 
=========================================

1. Tools > Chapter Numbering
2. Load /Save - Save As (opens dialog box, click Ok)
3. Repeat step 2 multiple times.
4. Crash.

The crash report here appeared after doing this 28 times in a row.

Here is another report, from using the same procedure (I did not count how many
times, but it was probably around 20-30 times).  But notice that the reason is
different: EXCEPTION_ACCESS_VIOLATION_READ 

https://crashreport.libreoffice.org/stats/crash_details/d49dc582-96a6-4e83-a883-abac145358a8

Both times this was conducted in Safe Mode with

Version: 7.2.0.0.alpha0+ (x64) / LibreOffice Community
Build ID: 7752bbe121fa0cd892ffc6ddaf465f519573dc09
CPU threads: 8; OS: Windows 10.0 Build 19041; UI render: Skia/Raster; VCL: win
Locale: en-US (en_DK); UI: en-US
Calc: threaded


Additional Information:

1. In "regular" mode, I got a crash from using Save As a single time.  So -- to
be sure it was not just a user profile problem, I attempted in Safe Mode.  Of
course, users will not use Save As 28 times in a row, but presumably there is
an implementation problem that needs to be examined, which might be related to
bug 140528.
