尝试编写自定义Allocate_Shared分配器并将其变为thread_local时崩溃

我的程序使用make_shared在每个线程中非常频繁地创建和破坏几种类型的小对象，并且共享_ptr不会传递给另一个线程，在这种情况下，我决定去用boost :: pool编写自定义Allocate_Shared分配器作为其成员，以根据类型分配固定的内存大小。

我的代码如下：

quadallocator.h：

#include <boost/pool/pool.hpp>
template<typename T>
class ObjectAllocator
{
public:
    typedef std::size_t size_type;
    typedef std::ptrdiff_t difference_type;
    typedef T* pointer;
    typedef const T* const_pointer;
    typedef T& reference;
    typedef const T& const_reference;
    typedef T value_type;
    auto static constexpr block_size=64+sizeof(value_type);
public:
    ObjectAllocator() noexcept:pool_(block_size){}
    ObjectAllocator(const ObjectAllocator &other) noexcept :pool_(block_size){}
    ~ObjectAllocator()=default;
    template<typename U>
    ObjectAllocator(const ObjectAllocator<U> &other) noexcept :pool_(block_size){}
    template<typename U>
    ObjectAllocator& operator= (const ObjectAllocator<U> &other){
        return *this;
    }
    ObjectAllocator<T>& operator = (const ObjectAllocator &other){
        return *this;
    }
    template<typename U>
    struct rebind{ typedef ObjectAllocator<U> other; };
    T *allocate(size_type n, const void *hint=nullptr){
#ifdef _DEBUG
        assert(n==1);
#endif
        return static_cast<T*>(pool_.malloc());
    }
    void deallocate(T *ptr, size_type n){
#ifdef _DEBUG
        assert(n==1);
#endif
        pool_.free(ptr);
    }
private:
    boost::pool<> ObjectAllocator<T>::pool_(block_size);
}
template<typename T, typename U>
inline bool operator == (const ObjectAllocator<T>&, const ObjectAllocator<U>&){
    return true;
}
template<typename T, typename U>
inline bool operator != (const ObjectAllocator<T>& a, const ObjectAllocator<U> &b){
    return !(a==b);
}

namespace Allocator {
template <typename T>
thread_local ObjectAllocator<T> allocator;
}

main.cpp：

class ObjectA{
public:
    int s=0;
    void func(){
        std::cout<<s<<std::endl;
    }
    ObjectA() {//std::cout<<"()"<<std::endl;}
    ~ObjectA() {//std::cout<<"~"<<std::endl;}
};
std::vector<std::shared_ptr<ObjectA>> vec;
void test(){
    static uint32_t loop_count=1000*1000;
    for(uint32_t i=0;i<loop_count;i++){
         shared_ptr<ObjectA> packet = allocate_shared<ObjectA, ObjectAllocator<ObjectA>>(Allocator::allocator<ObjectA>);
         vec.push_back(packet);
    }
    vec.clear();
}
std::vector<std::shared_ptr<ObjectA>> vec2;
void test2(){
    static uint32_t loop_count=1000*1000;
    for(uint32_t i=0;i<loop_count;i++){
        shared_ptr<ObjectA> packet = allocate_shared<ObjectA, ObjectAllocator<ObjectA>>(Allocator::allocator<ObjectA>);
        vec2.push_back(packet);
    }
    vec2.clear();
}
int main() {
    std::thread thread1(test);
    test2();
    return 0;
}

当我尝试测试它时，它会崩溃，我不知道为什么。谁能帮助使它正确？预先感谢。

调试器在shared_ptr_base.h

void* _m_get_deleter（const std :: type_info＆amp; __ti）const noexcept {return _m_pi？_m_pi-> _ m_get_deleter（__ ti）：nullptr;}

当我尝试使boost :: poost静态时，它在单线程中正常工作，并且在多线程中崩溃调试器说shone_ptr_base.h

：_M_USE_COUNT（1），_M_WEAK_COUNT（1）{}

更新：我将BOOST :: pool是静态thread_local，并且现在正常工作
