Because of the hint to Bug 105118 (GDI problem) I have made new tests with the
spreadsheet document "Test_Comment_Crash.ods" attached to Bug 105376.

Result: I think that the first "Save" or "Autosave" creates very much GDI
objects.

First I have increased the GDI quote in Windows from 10000 to 60000 to prevent
the crashes (and reatarted the system to activate the change). A new test with
my document gave no crash (but after document was saved and LO should be
closed, shutdwon of LO was hanging - see bug 105055). 

Then I have "installed" Nirsoft GDIView to see the GDI objects counter at
further tests.

The counters I have seen at the several tests were not exactly the same, but
they were in the same ranges always. The figures below are from one of the
tests. 

When the document was opened and I had navigated to the first sheet ("Altix I
bis III") the GDI counter ("All GDI") was 125. After the four first comments
were inserted and before the document was saved the GDI counter was 255.
This means that every comment has increased the counter by 27 or 28, although
the comments are hidden. I don't if this correct or not. Because the comments
are not shown I think only the bitmanp counter should be increased by 1. 

While the document was saved the GDI counter has extremly increased from 255 to
9873!!!

After some additional comments have been inserted the old limit of 10.000 was
exceeded.

Interestingly:
- Only at the first save (or maybe also Autosave) the GDI counter increases
extremly. At additional saves the counter has not increased or increased only
slightly. 
- At "Undo" the GDI counter does not decrease and at "Redo" it does not
increase.

These tests were made with LO 5.3.0.2 (x64).
