Created attachment 193279 [details] A sample DOCX with a huge floating table in a header In MS Word: 1. Create a new document; 2. Type 'foo', to make a non-empty body; 3. Add a header; 4. In the header, insert a table with 100 rows; 5. In that table's properties, set "Text wrapping"->"Around"; 6. Save as a DOCX. Try to open the DOCX in Writer. In v.4.4, this opened without a hang. Starting with v.5.0, it hangs.
Created attachment 193280 [details] A table cell with multiple paragraphs in a header Another infinite layout loop, possibly related. This one allows interaction with the document while looping, though.
Thank you for reporting the bug. When I try to open the sample DOCX with a huge floating table in the header, it doesn't open and freezes up, forcing me to end the process. I tried a new document with the steps to reproduce, and I seem to have no issues with opening it.

Hello Mike Kaganski, When I tried opening the sample DOCX file with a huge floating table in a header, I'm unable to open it in both the stable and master/daily build. Just like wsjim, I had to force quit both applications as they had stopped responding. I used the following two builds: Stable Build Version: 24.2.1.2 (AARCH64) / LibreOffice Community Build ID: db4def46b0453cc22e2d0305797cf981b68ef5ac CPU threads: 10; OS: macOS 14.1.2; UI render: Skia/Metal; VCL: osx Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded Master/Daily Build Version: 24.8.0.0.alpha0+ (AARCH64) / LibreOffice Community Build ID: c4023d3ec604abfff38be2053e2989c7ec2ba8c1 CPU threads: 10; OS: macOS 14.1.2; UI render: Skia/Metal; VCL: osx Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded
(In reply to Haris from comment #4) Indeed; that is the issue here. The title of this bug is "A huge floating table in header makes Writer hang". it is intended to say that the program hangs (freezes). Obvious, isn't it?
Since both wjsim and I can both reproduce it, I'm setting this to 'NEW'.

Concerning bibisect, it doesn't hang in latest of bibisect-50max, but hangs in oldest of bibisect-linux-64-5.2, needs to be bibisected on Windows.
