Target 3.x, as I still can't imagine how this should occur without API calls or
other threads.

You get the same crash if you load a file and manually delete a column? No API
calls or other threads involved? Then I can't imagine why there is an object
with refcount 0 to begin with.

We found another way to reproduce this crash, see
https://bugzilla.novell.com/show_bug.cgi?id=396605

I was not able to reproduce it by the Sun's OOo-2.4.1rc2 build. I am not sure if
it is ooo-build-specific or if it works in the Sun's build just by chance.

Is anyone more familiar with that code?

Search the valgrind log for "cellsuno.cxx:1642" to find the revelant part.

I tested the build based on ooh680-m16 sources and ooo-build-2-4-1 branch. It
crashed on the C# sample that could be found in 
/odk/examples/CLI/CSharp/Spreadsheet

The crash happend in sc/source/ui/unoobj/cellsuno.cxx in
ScCellRangesBase::Notify when it tried to call

 RefChanged();

The attached backtrace shows that the object this did not exist at that time.
More dubugging showed it was most likely removed on the end of

 ScTableSheetObj::getImplementation( (cppu::OWeakObject*)this )

Note that the method is defined the following way:

 ScTableSheetObj* ScTableSheetObj::getImplementation( const 
 uno::Reference xObj )

so there is created the temporary uno::Reference. The object "this" was probably
destructed together with this temporary reference.


I'll attach a patch that makes sure that the temporary object lives a bit
longer. It is only a workaround. I am not sure how it is supposed to work.
