当我在Visual Studio 2015中运行此代码时，代码可以正常运行，但是代码在代码块中生成以下错误：分段错误（核心已转储）。我也用同样的错误在ubuntu中运行了代码。

#include <iostream>
#include <immintrin.h>

struct INFO
{
    unsigned int id = 0;
    __m256i temp[8];
};

int main()
{
    std::cout<<"Start AVX..."<<std::endl;
    int _size = 100;
    INFO  *info = new INFO[_size];
    for (int i = 0; i<_size; i++)
    {
        for (int k = 0; k < 8; k++)
        {
            info[i].temp[k] = _mm256_setr_epi8(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,
                20, 21, 22, 23, 24, 25, 26, 27, …

考虑C ++中的以下代码片段：（Visual Studio 2015）

第一块

const int size = 500000000;
int sum =0;
int *num1 = new int[size];//initialized between 1-250
int *num2 = new int[size];//initialized between 1-250
for (int i = 0; i < size; i++)
{
    sum +=(num1[i] / num2[i]);
}

第二块

const int size = 500000000;
int sum =0;
float *num1 = new float [size]; //initialized between 1-250 
float *num2 = new float [size]; //initialized between 1-250
for (int i = 0; i < size; i++)
{
    sum …
