普通に質問の内容を再現すればだいたいこうなる

typedef struct tag_aho_list_t {
　　char new[0x10];
　　t_aho_list_t* next;
} t_aho_list_t;

ptr_new = (t_aho_list_t*)malloc(sizeof(t_aho_list_t));
strcpy(ptr_new->name, "aho1");
ptr_before = ptr_now;
ptr_now = ptr_new;
ptr_before->next = ptr_now;

ptr_new = (t_aho_list_t*)malloc(sizeof(t_aho_list_t));
strcpy(ptr_new->name, "aho2");
ptr_before = ptr_now;
ptr_now = ptr_new;
ptr_before->next = ptr_now;
