Different scenarios under which system hangs

1) printing pp() inside scheduler_tick() probe handler.
========================================
probe kernel.statement(0x000000000003b83c).absolute {
                funcname = pp();
      printf("========%s \n",funcname);
        }
==============================
2)printing probefunc() inside scheduler_tick() probe handler.
========================================
probe kernel.statement(0x000000000003b83c).absolute {
                funcname = probefunc();
      printf("========%s \n",funcname);
        }
==============================


Different scenarios under which system works well.
1) printing "hello" message  and calling probefunc() or pp()(without printing
their value) inside scheduler_tick() probe handler.
========================================
probe kernel.statement(0x000000000003b83c).absolute {
                funcname = probefunc();
      printf("hello");
        }
==============================
