             Bug #: 47320
           Summary: EasyHack: DrMemory windows warning cleanup ...
    Classification: Unclassified
           Product: LibreOffice
           Version: LibO Master
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED
          Severity: major
          Priority: medium
         Component: Libreoffice
        AssignedTo: libreoffice-bugs at lists.freedesktop.org
        ReportedBy: michael.meeks at novell.com


We regularly run LibreOffice and our extensive test suite through valgrind on
Linux, which dungs out -tons- of errors and problems.

However - on Windows, we don't get anything like the same level of coverage.

If you install 'DrMemory' - http://www.drmemory.org/ (choose to add it in your
path works best).

Then run:

drmemory -- soffice.exe

You should get a long slew of uninitialized warnings, and wrong malloc/delete
pairings and so on I'll attach a very limited sample of these. You really want
to install a pre-compiled Windows build from libreoffice-3-5-1 with debugging
symbols:

http://dev-builds.libreoffice.org/win32-debug/

Then you can get nice precise stack traces. Then it'd be great to try to hunt
down the errors. Unfortunately uninitialized memory errors can be hard to find
- they can propagate through the code at great length, and need tracing right
back to the first non-initialization.

Thanks !
