Created attachment 134630 [details] gdb output of multiple stack traces I experienced a hang while editing a Word document. The CPU load by Writer was at 100%. I waited for about 20mins but Writer never recovered. I am not able to reproduce the problem at will. Writer hung and stopped responding while I was typing. The document I edited is confidential so I cannot share it. It contains mainly text in a huge table with about 50 rows spanning multiple pages. There is just one or two graphics on the top page. There is nothing else of particular note in the document, in particular no formulas etc. While it hung I attached with gdb and interrupted and collected a full backtrace. Debugging symbols are mostly installed. Then I repeated the following a few times: I let Writer continue briefly and paused it again with gdb to collect a full backtrace. Attaching the gdb ouput, hoping it can be put to good use.
Thank you for reporting the bug. it seems you're using an old version of LibreOffice. Could you please try to reproduce it with the latest version of LibreOffice from https://www.libreoffice.org/download/libreoffice-fresh/ ? I have set the bug's status to 'NEEDINFO'. Please change it back to 'UNCONFIRMED' if the bug is still present in the latest version.
I cannot reproduce at will, so closing this case.
