问使用指向main中变量的指针的Pthread段故障EN解题思路：在主函数中声明了struct student类型，然后定义了一个struct student类型的变量s_1，又定义了一个指针变量p，它指向一个struct student类型的对象，将结构体变量s_1的起始地址赋给指针变量p，也就是使p指向s_1，然后对s_1的各个成员赋值。
Hello, I'm having problems with thread_local variables when the build is performed without -pthread and with -flto enabled. I've noticed that when the runtime arrives at a thread_local variable, there is a crash. It seems like the variab...
