However, it doesn't in

LibreOffice 3.3.0 
OOO330m19 (Build:6)
tag libreoffice-3.3.0.4

kind of an old regression...
Comment 5 Buovjaga 2019-01-25 11:54:47 UTC
I got a different result: no hang in 4.1-4.4. Bibisected with 50max to the Timer/Idle range, which seems fitting: https://gerrit.libreoffice.org/plugins/gitiles/core/+log/e6e8a060ecc6e4fd51cfe88e00d841d546ed5915..01f406bc28f53acc5a2734af637aa8074a5d1813

It was not a straight up hang, it just got very slow. I was able to quit normally each time.

Thanks for bibisecting. These types of bibisects are the most frustrating ones to do.
