<pre>Description:
When Calc NLP Solver is started for non-linear optimization, which takes more
than an hour (DS-PSO agent) it is working. In parallel, a Write document is
opened, edited, saved, and closed. When optimizations finish and "Keep Results"
button is pressed Calc crashes. Opening LibreOffice gives a dialog for
documents recovery. The optimization results are kept during the crash.
Optimization results are not lost, but after the general crash of LibreOffice
other open documents are also affected. I have looked at Calc's nlpsolver
module and I see some document lock instructions. I suppose that such locking
may be causing the crash.
Steps to Reproduce:
1. Open Calc and start NLP solver with DE-PSO agent for long-run optimization.
2. Open Write document, write something, save the document, close the document.
3. Wait for optimization to finish and press the Keep Results button.
Actual Results:
General crash of LibreOffice.
Expected Results:
Optimization results to be kept and Calc document to be editable and savable.
Reproducible: Always
User Profile Reset: No
