最近，其他人升级了我们的boost库，现在当重调用read_json函数时，我看到了这个coredump。以前从未见过。而且我在代码中有#define BOOST_SPIRIT_THREADSAFE，这就是为什么以前没有发生过。真的需要帮助!谢谢!
程序终止于信号11，段错误。

最佳答案
无论您在包含json_parser.hpp还是Spirit的任何地方，都必须定义BOOST_SPIRIT_THREADSAFE。如果boost/yourApp的另一部分在您不知情的情况下使用Spirit，则在全局定义它是最安全的。
对于任何未定义的包含，Sprit都会在grammar.ipp中创建一个静态变量，该变量将在Spirit的所有实例之间共享。您的grammar_destruct错误是因为Spirit在您的一个模块中缺少此定义。
