Boost 当校准被禁用时，Eigen3增压MPFR SEGFULT

boost

Boost 当校准被禁用时，Eigen3增压MPFR SEGFULT,boost,c++14,eigen3,mpfr,Boost,C++14,Eigen3,Mpfr,当我尝试使用Boost.Multiprecision来包装MPFR和禁用Eigen的对齐假设时，我遇到了一个奇怪的segfault问题 示例测试代码： #include <boost/multiprecision/mpfr.hpp> #include <Eigen/Dense> #include <iostream> int main(int argc, char** argv) { typedef boost::multiprecision::numb

当我尝试使用Boost.Multiprecision来包装MPFR和禁用Eigen的对齐假设时，我遇到了一个奇怪的segfault问题

示例测试代码：

#include <boost/multiprecision/mpfr.hpp>
#include <Eigen/Dense>
#include <iostream>

int main(int argc, char** argv)
{
  typedef boost::multiprecision::number<
    boost::multiprecision::mpfr_float_backend<71,
      boost::multiprecision::allocate_stack>,
    boost::multiprecision::et_off>
    real256;

  Eigen::Matrix<real256, 9, 9> mat;
  // set mat to identity matrix
  for (size_t i = 0; i < 9; ++i)
  {
    for (size_t j = 0; j < 9; ++j)
    {
      mat(i, j) = 0;
    }
  }
  for (size_t i = 0; i < 9; ++i)
  {
    mat(i, i) = 1;
  }
  std::cout << mat << std::endl;
  Eigen::Matrix<real256, 9, 9> mat2 = mat2.inverse();
  std::cout << mat2 << std::endl;
}
但是，当我尝试禁用eigen的对齐假设时，它会在反向计算过程中出错

g++ mat_test.cpp -L/usr/lib/x86_64-linux-gnu -lmpfr -I/usr/include/eigen3 -DEIGEN_MAX_ALIGN_BYTES=0 -o mat_test
请注意，如果我将矩阵更改为保持双精度或浮点值，则不会发生此SEGFULT。我注意到boostmultiprecision的MPFR包装中曾经有一个bug，其中自我分配会导致奇怪的问题，但是我相信我正在使用一个足够新的Boost版本，这应该得到修复（1.65.1）

我在定义Boost MPFR类型时使用的特定选项是否有一些特定的东西与Eigen产生了负面影响

我尝试使用gdb来跟踪问题发生的位置，但我无法真正理解实际问题是什么

以下是我从gdb获得的堆栈跟踪：
