Can a LibreOffice-edited document cause another user's Office 365 to crash?

I am a relatively new LibreOffice user. This week someone sent me a document written in Word, sent it to me by email, I then updated it using tracked changes and comments and sent it back by Skype. When my client opened the document it caused her Office 365 to crash. This is how she explains it:

"I opened the revised version of the document which I downloaded from here on Skype. It kept crashing my Word app. I reinstalled office etc., copied the content into a new doc, etc. No luck. I first thought it might be a Skype/Word issue, but in the end, when I saved it in an older Word version, it allowed me to make changes without crashing. Thought I’d let you know because it may be linked to the system you are using (only compatible with the older Word version) and others might experience the same? "

I find it hard to believe that LibreOffice is only compatible with older Word versions. Could it be something else? Anyone else experienced this? Thanks for your help.

FYI: it’s not uncommon that later MSO versions impose new restrictions (sometimes contradicting the format specifications) and start crashing on data that was handled gracefully by older versions; the advise by @Hrbrgr to file a bug report is the best route

When filing the report, make sure to attach a file before edits in LO to the bug as the sample; and provide the steps to create the crashing document (i.e., which edits and where are needed). Only then will we be able to understand what causes the output that crashes Word; a file with that output already present often has no value for understanding how to prevent it from happening. Thanks!

Please write a bug in Bugzilla.

Give details about the Office versions used and the operating system versions used.

Describe the procedure that leads to errors very accurately.

Add a test file where the error occurs.

Write the link to the bug here in your question. To do this, edit your question.

Many thanks.
