Description

When I use a static thread_local object in thread, the object's destructor is not called after the thead exit. The sample code is as follow. Is ndk don't support TLS?

static void threadLocalTest() {
    class Demo {
    public:
        Demo() {
            ALOGD("Demo()");
        }
        ~Demo() {
            ALOGD("~Demo()");
        }
    };

    auto func = []() {
        static thread_local Demo demo;
    };

    std::thread t1(func);
    std::thread t2(func);
    t1.join();
    t2.join();
}
