Description Octavio Alvarez 2016-10-10 20:47:11 UTC
Writer goes hangs with high CPU and the only way to proceed is to kill it after the following steps.

Steps to Reproduce:
1. Copy all content from bug-content.odt:
   - Open bug-content.odt, Ctrl+A, Ctrl+C.

2. Open bug-new-template.odt.

3. Open the Styles and Formatting side pane.
   - F11

4. Paste it at the end of bug-new-template.odt:
   - Ctrl+End, Ctrl+V.

Observe how the original A to D content is now 1 to 4 on both questions. This is probably a bug. However it is not the bug I am reporting.

5. Select the first set of possible answers, the ones that include 100, 200, 300 and 400 as options. Select them from the start of "100" to the end of "400".

6. Double click on style "Pregunta".

Actual Results:  
Writer goes hangs with high CPU and the only way to proceed is to kill it.

Expected Results:
Writer should apply the style Pregunta.

Reproducible: Always

User Profile Reset: No

I'm reattaching bug-content.odt with a description that better matches the bug report.

@Meeks, @Maxim: Is a trace needed for this?

On pc Debian x86-64 with master sources updated yesterday, I could reproduce this.
I noticed this log repeatedly:
warn:legacy.osl:2401:1:sw/source/core/layout/flowfrm.cxx:2405: <SwFlowFrame::MoveBwd(..)> - layout loop control for layout action <Move Backward> applied!
