Hello and thank you for reporting this issue.

Unfortunately, it seems to be an instance of a known problem with the current 
Raptor source base (multithreading problems where several parts of the program 
are working on the same data items without proper synchronization) and there 
will be no quick fix because it would take much more time to fix those problems 
than I currently want to spend on Raptor maintenance.

Regards.
