    Description

      in mysql_stmt_fetch_column function have follow code

          if (bind[0].length)
      		 
            *bind[0].length= stmt->bind[column].length_value;
      		 
          else
      		 
            *bind[0].length= *stmt->bind[column].length;

      if bind[0].length ptr is NULL, else branch will coredump

      The right code maybe

          if (bind[0].length)
      		 
            *bind[0].length= *stmt->bind[column].length;
      		 
          else
      		 
            bind[0].length= &stmt->bind[column].length_value;
