如标题所述，我发生了段错误，我不知道为什么。我可以挖掘的最接近的可能相关问题是this。我的系统规格如下：

  • RHELv5u8
  • icpc 12.1.0 版（gcc 4.1.2 版兼容性）
  • 拱 = x86_64

使用g++编译时似乎没有出现问题。

我已将问题隔离为一小段代码：

#include <iostream>
#include <cstdio>
#include <vector>

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/vector.hpp>
#include <string>
#include <fstream>

using namespace std;

int main()
{   
  cout << "Testing ... ";

  vector<int> outVect(10);

  //  Save the data
  std::ofstream outputFile_("archive.txt");
  outputFile_ << std::scientific;
  boost::archive::text_oarchive textOutArchive_(outputFile_);
  cout << "chk1" << endl;
  textOutArchive_ & BOOST_SERIALIZATION_NVP(outVect);
  cout << "chk2" << endl;
  return 0;
}

我正在编译：

icpc -g -static -openmp standalone.cc -o minimal -lboost_serialization ; ./minimal

有任何想法吗？

Valgrind 给了我以下信息：

长评：

pthreads除非链接整个存档，否则静态链接（由 OpenMP 运行时使用）永远不会正常libpthreads.a工作。要解决它，您应该附加-Wl,--whole-archive -lpthreads -Wl,--no-whole-archive到编译选项。

但是，我在您的代码中看不到并行区域，因此激活 OpenMP 是多余的。此外，它看起来更像是 RTTI 在 icpc 上失败，因为错误发生在从内部调用的东西中extended_type_info_typeid.hpp。
