即使在逻辑上对两个错误条件进行逻辑运算后，断点处的GDB复杂条件也变为true

Question

如果有条件的条件断点

  (gdb) b handle.cpp:66 if ( (sn == 6092 && !strcmp(_name.c_str(),"HSI_IDX_DEF")) || (sn == 1251 && !strcmp(_name.c_str(),"SP_IDX_DEF")))

它每次都会命中，因为即使对两个错误的子条件进行运算后，复杂的条件也会每次都变为真。

(gdb) p  ( (sn == 6092 && !strcmp(_name.c_str(),"HSI_IDX_DEF")) || (sn == 1251 && !strcmp(_name.c_str(),"SP_IDX_DEF")))
    $10 = true
    (gdb) p (sn == 6092 && !strcmp(_name.c_str(),"HSI_IDX_DEF"))
    $11 = false
    (gdb) p  (sn == 1251 && !strcmp(_name.c_str(),"SP_IDX_DEF"))
    $12 = false
