"Segmentation fault" during tns rman active duplicate

Question

Hello. I am trying to do an active duplicate using tns connectivity and just after restoring the controlfile the process fails with the error "Segmentation fault". However if I start the rman using Ezconnect everything goes smoothly. Restarting the databases did not help. What could be the reason? Here is the output with the error:
