关于mingw thread_local

#include <iostream>
#include<thread>
class ObjectPool{
public:
size_t len = 0;
size_t capacity = 128;
size_t start = 0;
static ObjectPool& getInstance(){
static thread_local ObjectPool pool;
return pool;
}
~ObjectPool(){
std::cout << len << std::endl;
std::cout << capacity << std::endl;
std::cout << start << std::endl;
}
};
int main(){
auto func = [](){
std::cout<<"thread:"<<std::this_thread::get_id()<<std::endl;
auto& pool = ObjectPool::getInstance();
};
std::thread t(func);
t.join();
}

似乎是由于static thread_local对象内存清理先于析构函数调用，在GDB中表现为在调用析构函数前用0xFEEE填充内存。这个bug的历史有接近十年了，直到现在仍然没有修复

为什么要加thread-local呢？你都用c++11了，这种情况static 带锁。
