CAS program corrupts itself

No, it happens no matter what's in the loop. Even this gets corrupted:

Code:


(x)->BEGIN  
  FOR x FROM 1 TO 10000000000 DO x:=x; 
  END; 
  RETURN(x);  
END;

When interrupted by pressing On, the above turns into this:

Code:


(x)->BEGIN  
  FOR x FROM 1 TO 10000000000 STEP "Stopped by user interruption. Error: Bad Argument Value" DO x:=x; 
  END;;  
  RETURN(x);  
END;

What really scares me is this: delete the corrupted program, re-create it from scratch, exit the program editor, and before even running it, go back and look at it... it will already be corrupted (usually with the TO turned into DOWNTO). So this bug not only corrupts the running program, but corrupts programs that haven't even been written yet! It's a tunneling tachyon emitter! Vewwy, vewwy scawwy!
