Calc Crashes when "Sorting" on mac osx 10.10 -not on windows 10 (LibreOffice 5.0.0)

main data sheet 6000 rows 20 columns calc document.
Created and saced always by libreoffice since 3.4.4.
second sheet is 100 rows and 20 columns.
Sort key would be Column:12
Format: Date.
Always crushes…

need to mention that everything was fine few months ago. I was using LibreOffice 4.3
4.4 and 4.5 and 5.0 are all the same by means of crash issue.

Correction: Everything works under 4.4.3.2. Newer versions problem.
