在谷歌基准测试中生成/加入线程时的核心转储

Question

我在尝试生成然后加入 google 基准测试中的线程时得到核心转储。这与我尝试创建的线程数量无关。

重现问题的代码：

void BM_ThreadsTest(benchmark::State &state)
{
  std::atomic<size_t> curr_processed {0};
  constexpr size_t max_processed = 100;
  constexpr size_t NUM_CORES = 24; //get programmatically
  std::vector<std::thread> threads;
  while (state.KeepRunning())
  {
    for (int i = 0; i < NUM_CORES; i++){
      threads.push_back(std::thread( [&curr_processed, &max_processed]() {
        while (curr_processed <= max_processed)
        {
          curr_processed++;
        }
      }));
    }
    for (auto &th: threads){
      th.join();
    }
   }
  }
  BENCHMARK(BM_ThreadsTest);
  BENCHMARK_MAIN();

错误：

terminate called after throwing an instance of 'std::system_error'
  what():  Invalid argument
Aborted (core dumped)
