Description:
When opening a

Steps to Reproduce:
Unable to reproduce with 6.2.8.2. Did not test any versions between this and 6.3.6.2. Able to reproduce with 6.3.6.2+ through to latest 7.2.0.1

1. Open the provided .doc file

Alternatively:

1. In Microsoft word, create a blank document
2. Add a table with 3 rows, and 2 columns
3. Click and drag to increase the height of the first row
4. Select the 3 cells of the left column
5. Merge the cells
6. Add text to the merged left cell
7. Rotate the text so that it is vertical
8. Left-Center align the text of the left column
9. Enter text into the first row of the right column
10. Enter text into the middle row of the right column
11. Add enough newlines into the right middle cell so that the cell spans the entire first page and continues onto the second
12. Add more text to the bottom of the middle right cell
13. Add text to the bottom right cell
14. Save the document using the .doc extension (Word 97-2003)
15. Attempt to open the document using LibreOffice 6.3.6.2 or newer

Actual Results:
LibreOffice process stops responding.

Expected Results:
LibreOffice should not hang/crash/stop responding.

Reproducible: Always

User Profile Reset: Yes

Additional Info:
I believe this type of table formatting is not natively supported by LibreOffice. How this content is displayed is not the issue, only the process hanging.

Comment 3 Aron Budea 2021-07-26 04:08:08 UTC

The documents opens fine in 6.2 and older, the hang during fileopen started with the following commit, bibisected using repo bibisect-linux-64-6.3. I'm inclined to believe the change just uncovered an issue already present in document layouting, there are somewhat similar issues, eg. bug 121720.
