> I was able to reproduce the crash with the following configuration:
> AOO Version: AOO411m6 (Build:9775)  -  Rev. 1617669
> Machine: Windows 7 (service pack 1) AMD Athlon II P320 2.10 GHz 3.75GB
> usable RAM
> 
> Unfortunately the Error Report Tool did not launch with this crash in this
> version of the app. 
> 
> Why am I adding another comment?
> This report has 26 comments spanning 5.5 years and it is still UNCONFIRMED.
> I hope my comment contains enough new information to help progress the bug
> towards some resolution.
> 
> Steps to reproduce
> I have been able to reproduce the crash 100% of the time with the following
> steps.
> Required: Impress presentation with an image > 1mb on 1 slide. I used
> attached 1129kb-image-crash.odp
> 1.    Open attached 1129kb -image-crash.odp (contains 1 slide with 1 static
> image)
> 2.    Copy & paste slide (keyboard shortcuts, right click options or menu
> options)
> 3.    Paste slide again (no need to copy again)
> 4.    Impress crashes
> 
> This is similar to the behaviour observed in Comment 8; only I had to
> include a large image (1.1mb)
> 
> Also, the test above is similar to Test 2 in Comment 17 (which did not
> reproduce the crash), but again I used a larger image (1.1mb vs I assume
> 70kb)
> 
> The crash was also observed with the following deviations from the steps
> above when running follow up tests:
> •     Creating a new presentation and inserting multiple large images (how I
> created 1129kb -image-crash.odp)
> •     Create a new slide & copy image from slide 1 to that new slide
> •     With 2 slides, both with the same large image, attempt to copy 2nd slide
> 
> The crash was not observed when repeating the following tests 
> •     Follow steps above but with cut & paste instead of copy & paste (is this
> related to a buffer being overrun when copying which isn’t being overrun
> when cutting?)
> •     File sizes < 1mb did not crash Impress with the steps outlined above.
> (997kb-image-nocrash.odp)
> •     Mp4 files > 1mb (not even mp4 > 30mb!)
> 
> Further suggested follow up tests
> •     What different objects reproduce the behaviour (static images do, video
> files apparently don’t)
> •     Repeat steps with images closer to the 1000mb threshold
> •     What program options are available that might impact copy & paste
> functionality?
> •     Possibly altering system memory – although like previous commenters, my
> machine showed no CPU performance or memory spikes when Impress crashed
> 
> Speculation of underlying fault
> Is there a 1mb buffer that is being blown when copying? When cutting, I am
> assuming that the buffer is not being exceeded therefore the program does
> not crash.
> This is an assumption on behalf of the commenter. I was unable to get images
> closer to the 1000mb threshold, nor see the size of the content on the
> clipboard.
> 
> Customer Impact / bug importance
> Quality & therefore size of media is growing & has grown immensely over the
> past 5 years – think of the smartphone & the associated camera quality wars.
> Also a similar increase in the DSL camera market.
> 
> People are taking high quality photos & recordings & they want to use those
> in presentations to show off their work to the best of their abilities.
> The range of different images & other media being used  is greater than when
> this bug was raised – what does that mean for it’s importance?
> There are even example use cases  in the comments in this bug outlining how
> those commenters are using Impress (e.g. comments 25 & 26)
> 
> Other notes
> •     On recovering the document, the Error Report Tool did not automatically
> open as the message informed me it would.
> •     Some of the comments are distracting from the investigation of this bug,
> such as comment 26 which appears to be related to exporting to pdf (see
> issue 101669)
