即使在逻辑oring两个假条件之后，断点中的GDB复杂条件也变为真

如果已读取带有条件的条件断点

  (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，因为即使在对两个假子条件进行oring之后，复杂条件每次都变为真

(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

太糟糕了，不可能是真的。你能用值而不是变量名发布你的gcc/gdb版本、操作系统、变量值和条件结果吗？@kelter:添加了信息。无论如何，这不是什么高级bug。这很简单，就好像| |环不能正常工作一样。虽然这可能是一些旧版本中的错误。有人不得不问一个愚蠢的问题：优化是否被禁用？另外，请尝试写入条件并检查代码并运行；这些附加测试将有助于您的调试。请在不使用c_str（）的情况下进行尝试-在此之前进行计算，并在打印中使用表达式或常量字符串值。
