2. while fixed has more performance at fix bwos queue bug #1752
   `
   template <class Tp, class Allocator>
   lifo_queue<Tp, Allocator>::lifo_queue(
   std::size_t num_blocks,
   std::size_t block_size,
   Allocator allocator)
   : blocks_(
   std::max(static_cast<size_t>(2), std::bit_ceil(num_blocks)),
   block_type(block_size, allocator),
   allocator_of_t<block_type>(allocator))
   , mask_(blocks_.size() - 1) {
   blocks_[owner_block_.load()].reclaim();

// fixed by there.
blocks_[thief_block_.load()].head = block_size;
blocks_[thief_block_.load()].tail = block_size;
blocks_[thief_block_.load()].steal_head = block_size;
}
