Abnormal termination when too much memory specified for hash table program.

   ERROR: An unknown, abnormal error has occurred during execution at 
          line n column xx.
   ERROR: Termination due to Floating Point Exception

Explanation:

   proc options option=memsize value; run;

Hash tables have a known defect that causes SAS to issue the abnormal error message when the amount of memory overflows a 32 bit address.

A fix is planned for a future release.

Workaround

Reduce the amount of memory specified to 8G.

MEMSIZE System Option: Windows

MEMSIZE System Option: UNIX

Operating System and Release Information

If MEMSIZE is too large, this program produces an error.

If it runs without error, hash tables perform correctly.

data A;
 x=1; y=2;   
run;

data B;
 x=1; z=2;
run;


data match;
 length x y z 8;
  if _N_=  1 then do;
    declare  hash h(dataset: "A", ordered: 'no', hashexp:14);
    declare  hiter iter('h');
    h.defineKey('x');
    h.defineData('y');
    h.defineDone();
   call  missing(x,y);
  end;
                
  set B;
  if (h.find() eq 0) then output;
run;
