Hello Ferenc, Thank you for reporting the bug - it's very curious, I will look into it in the nearest couple of days.
Could you please send me privately the actual input file on which the program crashes? I have added a downloadable link to the presentation to all places where the slideshare link was present (finally making some use of my hosting...).
