The MEANS, SUMMARY, or TABULATE procedure might report incorrect values of the automatic output data set variable _FREQ_ when the procedure statement options THREADS and NOTRAP are specified. The _FREQ_ values might be incorrectly doubled. This problem is most likely to occur when a significant number of analysis variables are requested.

To circumvent the problem, remove either the THREADS or the NOTRAP option from the procedure statement.

* For software releases that are not yet generally available, the Fixed Release is the software release in which the problem is planned to be fixed.

When the MEANS, SUMMARY, or TABULATE procedure statement options THREADS and NOTRAP are set with a significant number of analysis variables requested, the automatic output data set variable _FREQ_ might be incorrectly doubled. The code below replicates the problem.

data test;
   array av[100];
   do i = 1 to 1e5;
      cv1 = int( ranuni( 123 ) * 2);
      do j = 1 to 100 ;
         av[j] = rannor( 456 ) * 100;
      end;
      drop i j;
      output;
   end;
run;

proc summary data=test missing nway notrap threads;
   class cv1;
   var av1-av35;
   output out=test2 n= sum= mean= / autoname;
