----------------------------------------
I got a segmentation fault, fllowed by the message "You may have encountered a bug in the Ruby interpreter or extension libraries.". See attachment. 

The exception occured in this piece of code:


  class EXPERT
    
    FIND_CHAIN_FOR_POS_FILTER_PIPELINE = 
      [ 
        :no_filter,
        :filter_by_etkz_e,
        :filter_chain_in_chain,
      ].each
    
    def find_chain_for_pos(sw_lines_for_module, wsc_sw_lines)
      
      FIND_CHAIN_FOR_POS_FILTER_PIPELINE.rewind        

      begin
        
        while NVP.multiple_grpids?(sw_lines_for_module)
          
          filter_method_symb = FIND_CHAIN_FOR_POS_FILTER_PIPELINE.next # <----- This is line 30, where the exception reportedly occured.
          
          sw_lines_for_module = NVP.send(filter_method_symb, br, sw_lines_for_module) 
          
        end
        
      rescue StopIteration
        
        LOG.trace "Could not find unique GRPID"
        
      end

    end
  end

The segmentation fault occurs only after this method has been executed repeatedly several hundred times.
