分段错误在预定义元素g_int_hash中

Question

我在程序中使用GHashTable来存储用户输入的文件中的字符串。 除了行

中的分段错误外，没有错误发生

GHashTable* HT = g_hash_table_new(g_int_hash, g_int_equal);

我从未在预定义元素g_int_hash中看到分段错误 错误：编程接收信号SIGSEGV，分段故障。 来自/lib64/libglib-2.0.so.0的g_int_hash（）中的0x0000003f2ec74b70

#include <cmdheader.h>
int main(int argc, char* argv[])
{

        int status = FAILURE;
        int i; //loop-counter
        char** safe_pointer = NULL;

        printf("before HashTable");
        GHashTable* HT = g_hash_table_new(g_int_hash, g_int_equal);

        if(argc < 2)
        {
                printf("\n <USAGE> : <Program_name> <file1> <file2> ...");
                return FAILURE;
        }
        // program needs to be scalable, all files should be read using variable arguments

        for(i = 1; i < argc; i++)
        {
                safe_pointer = &argv[i];
                status = read_CMD(safe_pointer, &HT);
