            Bug ID: 111561
           Summary: IOHIDDeviceClass::setElementDictIntValue() leaks
                    memory
           Product: LibreOffice
           Version: 6.0.0.0.alpha0+ Master
          Hardware: x86-64 (AMD64)
                OS: Mac OS X (All)

          Severity: normal
          Priority: medium
         Component: framework
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
When invoked

IOHIDDeviceClass::setElementDictIntValue() 

leaks memory quite substantially, as does :

IOHIDDeviceClass::createElement()

and these are invoked multiple times.


Steps to Reproduce:
1. Start XCode, then Instruments.app
2. Choose Memory Leak profile tool
3. Select LibreOffice.app in instdir as target process
4. Click on the record button, LODev is started by the profiling tool
5. Wait for the StartCenter to load - note the occurrences of memory leaks as
they occur.
6. Open a new Writer document.
7. When the document has loaded, click on the dropdown font list. Scroll up and
down the list with the Up/Down cursor arrows
8. Stop recording.
9. Analyse the profile trace.

Actual Results:  
It leaks memory

Expected Results:
It shouldn't leak memory


Reproducible: Always

User Profile Reset: No
