             Bug #: 53120
           Summary: LibreOffice crash when saving a large file from Writer
    Classification: Unclassified
           Product: LibreOffice
           Version: 3.5.5.3 release
          Platform: x86-64 (AMD64)
        OS/Version: Windows (All)
            Status: UNCONFIRMED
          Severity: critical
          Priority: medium
         Component: Writer
        AssignedTo: libreoffice-bugs at lists.freedesktop.org
        ReportedBy: michel at nallino.net


OS: Windows 7 Home Premium 64 bits SP1 (French)
Java: SE 7 U5 or SE 6 U33
System RAM: 16 GB
LibreOffice 3.5.5
Extensions: French, Spanish, Italian and English dictionaries; PDF import;
presentation minimizer.

Bug occurs with a large odt file (350 pages, 99 images, 232 MB). Once the file
is loaded, the RAM used by "soffice.bin" is some 130-160 MB. 

When saving the file the first time, it appears that "soffice.bin", as seen in
task manager, increases considerably the RAM it uses, up to 800-900 MB
(particularly at the end of the saving process, when the screen is freezed).
When the file is saved and the access to document is released again,
"soffice.bin" does not go back to its former RAM use, but uses some 250 MB
(even when not doing anything).

After each time the file is saved, the RAM used by "soffice.bin" is higher and
higher, up to 450 MB when not doing anything. From this state, at the next
saving of the file, the RAM used climbs up to 1.2 GB, and, once this amount is
reached, Writer / LibreOffice crashes.

Three to four successive saves of the file (including automatic saves) are
enough to go to the crash.
This resembles to a memory leak in "soffice.bin".
