Description brunoveilleux 2020-03-02 22:38:29 UTC 
Description:
When dealing with a paragraph that contains 3 lines separated by line breaks (not paragraph breaks), if I try to break it into exactly 3 columns by inserting a section with the default settings (auto width and evenly-distributed content), Writer hangs. Reproduces every time, but only with this combination of content and settings.

Steps to Reproduce:
This seems to happen only in specific circumstances, so I’m attaching a test file. I’ll call "test paragraph" the area at the top with this following text:
Préparation : 30 minutes
Cuisson : 10 minutes
Donne 36 tranches

Note that the first two lines end with a line break; the last line ends with a paragraph break.

1. Select the test paragraph.
2. Go to Insert > Section, in the Columns tab.
3. Set the number of columns to 3. Leave other options unchanged (auto width on, even distribution of content on; not sure how those appear in the English interface).
4. Click Insert.

Actual Results:
LibreOffice maxes out a CPU core and hangs indefinitely.

Expected Results:
Columns should be inserted normally.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
This bug seems extremely specific. If I make it 2 or 4 columns, it works. If I untick either auto-width or even content distribution, it works. If I only select two of the lines, it works (even if I make it 2 columns). If I change the line breaks to paragraph breaks, it works.

I’d rather not replace the version provided by my OS’s software manager, but this still occurs in 6.4.7.2 with the original test file.
