LibreOffice version 7.4.1 hangs while converting docx to pdf

When we try to convert certain docx files to PDF using libreoffice in headless mode, the process hangs and it starts consuming a lot of CPU almost 100%

Version: LibreOffice 7.4.1.2 40(Build:2)

Following is the output of strace of the process:

I am using UNO protocol to communicate with LibreOffice using the following command:

/usr/bin/soffice --nolockcheck --headless --invisible --nologo --nodefault --nofirststartwizard --display :5.0 --accept='socket,host=0.0.0.0,port=8100;urp;StarOffice.Service'

I have tried opening the same file in the desktop version of LibreOffice, it opens the file and then hangs after ~5 seconds. Also, I have tried on Ubuntu 20.04 and macOS 12.6.

Unfortunately, I cannot share the actual docx file because it has private data.

What happens if you try that with an older version? Please note that using the “fresh” version of LibreOffice for business is not recommended - it’s for the people who want to toy with the latest additions and want to test it for stability. Business users should use the “still” version, as of 2022/09/29 that’s 7.3.6.

So it is not happening for all docx-files ?
.
As you can not share the file, try to check the contents yourself. .docx is usually also a zip-file, so rename a copy to .zip and open it.
.
Or try to open the file with a good Editor, to check if it contains actually xml/html.
We’ve seen recently some cases of “database-reports” wich actually contained html and an xml-header to direct excel how to open the table. So there is a bunch of funny easter-eggs out there to be explored by you…

I tried converting the same document with Libreoffice 7.3.6 and I am still getting the same behaviour, following is the output of strace:

I tried installing few fonts but that too did not help.

@floris_v the old version of Libreoffice (7.6.3) also hangs while converting the document.

@Wanderer I don’t have much knowledge about docx file format, I decompressed the docx file but i was not able to find anything based on my limited knowledge.
I was able to reproduce the issue with a sample document that I am attaching here.

template.docx (163.6 KB)

The document is created using one of the templates provided my Microsoft Office called “Creative resume, designed by MOO”
