--- Comment #11 from Jon Grossart <jon at grossart.net> ---
I was able to create the crash again. There is no shortcut, you just have to
open and close a ton of dialogs until something stops working. It would
probably happen faster on a system with lower memory (I have 32 GiB). It might
be possible to record a macro to open and close the style window multiple times
to save on clicks.

WinDbg showed no exception at the time of crash, just a ton of runtime
exceptions that scroll basically any time you do anything in the program, but
the debugger doesn't stop then.

(2b04.1f44): C++ EH exception - code e06d7363 (first chance)

When the crash happened, the bugger did stop, but no real information showed up
in the analaysis.

However, proc explorer does show some interesting things:

9932 GDI handles -- when you start LibO with the same document opened I was
testing with, it shows 138 handles.

I don't think having 2 documents open should eventually end up with 2 GB of
working RAM with 8 GB of virtual size. Active RAM also went from 260 MB to 512
M
MB over the time of debugging. There is clearly some form of memory leak
happening.

For reference, just opening the same two documents with no editing:
Private Bytes: 421 MB
Peak Private: 1.15 GB
Virtual Size: 5.25 GB
Working Set: 260 MB
Hangles: 6559
GSI Handles: 178
USER Handlers: 229
