Crash issue due to refcount error with clang compiler

bool AbstractBuffersPool<PoolT, BufferType, BufferParentType>::isPoolBuffer(const BufferParentType *buffer) const {
    static_assert(std::is_base_of_v<BufferParentType, BufferType>);

    return (buffer && this->mainStorage.get() == buffer);   // for clang compiler, unique_ptr is assigned nullptr firstly
}
