vscode运行代码出错ERROR: GDB exited unexpectedly. Debugging will now abort.

Question

用Ubuntu20.04.5的vscode运行一个生成数据的代码，运行到图示位置时出错：
ERROR: GDB exited unexpectedly. Debugging will now abort.
The program '/home/zhang/project/MSFinal-master/BDMRS/gen_data' has exited with code -1 (0xf.).
经过断点运行判断是执行完循环后就出错，各位知道是什么原因吗？

这是define.h文件

/***
 * This code .h file define size and struct used.
 */

#define FILE_SIZE       500
// only 26*n is support due to invert matrix function
// only 26 and 676 add to git
#define DICT_SIZE       650
#define FILE_PATH       "../doc/FILE0001.txt"
#define MATRIX_PATH     "../Matrix/Matrix650trans.txt"
#define MATRIXinv_PATH  "../Matrix/Matrix650inv.txt"
#define SK_PATH         "./SK.txt"

// struct of node
typedef struct tree_node {
    int ID; // node ID
    double D[2][DICT_SIZE]; // index data
    struct tree_node *Pl; // pointer to left node
    struct tree_node *Pr; // pointer to right node
    int FID; // pointer to file, use file's ID here
} Node;

// max function
double max( double a, double b ){ return (a>b)?a:b; }

这是出现问题的gen_data.c文件

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <time.h>
#include "define.h"

/***
 * This code generate the data used in search
 */

int main() {
    int i, j;
    FILE *fp;
    struct stat st = {0};

    // initial the random seed
    srand( time(NULL) );
    // if no dir "doc", creat it
    if (stat("./doc", &st) == -1) {
        mkdir("./doc", 0700);
    }

    // for each file
    for( i = 0; i < FILE_SIZE; i++ ) {
        //initial file name
        char filename[] = FILE_PATH;
        char *ptr = strstr(filename, "FILE");
        sprintf(ptr, "FILE%04d.txt", i+1);
        fp = fopen(filename, "w");

        // for each keyword in file
        for( j = 0; j < DICT_SIZE; j++ ) {
            // initial keyword name
            char word[] = "aa";
            word[0] = 'a' + j / 26;
            word[1] = 'a' + j % 26;

            // generate keyword size, half set to 0
            int a = rand()%(DICT_SIZE*2) - DICT_SIZE;
            if( a < 0 ) a = 0;
            fprintf(fp, "%s %d\n", word, a);
        }

        // close file
        fclose(fp);
    }

    return 0;
}

Answer 1

两个地方改改试一下
第一个判断fp是否打开文件成功 函数调用最好判断下返回值
第二个设置word[2] = '\0'
