Destruction order of thread_local variables

 #include class C1{public:C1() { printf("c1cons\n"); }~C1() { printf("c1des\n"); }};class C2{public:C2() { printf("c2cons\n"); }~C2() { printf("c2des\n"); }};int main(int argc, const char *argv[]){thread_local C1 c1;thread_local C2 c2; // C2 is expected to be post-constructed and destructed first.Because semantically c2 may depend on c1 (eg c1 is a construction parameter of c2)return 0;}
