代码按预期工作,但它永远不会释放分配的内存malloc().

我试图在任何可以的地方释放记忆,但无论我在哪里,它都会破坏程序.具体来说,我得到了"双重免费或损坏错误".这更像是关于什么free()和malloc()实际做的问题？免费的所有问题主要在于:

int main(int argc,  char *argv[]){
if(argc!=2){
    exit(1);
}

printf("CSA WC version 1.0\n\n");

int length = strlen(argv[argc-1]);
char file_to_open[length];
strcpy(file_to_open, argv[argc-1]);

//printf("filename:%s\n",file_to_open);

//create counters for output
int count_number_of_lines = 0;
int count_number_of_words = 0;
int count_number_of_characters = 0;

//create int size of default array size
int current_array_size = pre_read(file_to_open);
//printf("number of lines: %i\n",current_array_size);

//create string array of default size
char *strings_array[current_array_size];

//create a pointer to catch incoming strings
char *incoming_string=NULL;

int done=0;
while(done==0){ …

我已经阅读了大约十亿次,我无法弄清楚...我在工作台中生成了它,所以它应该可以工作,但它会创建除了SECTIONS之外的所有表...如果我删除之间的关系它会创建它部分和讲师,但我需要这种关系工作....任何帮助将不胜感激!代码如下...希望有人可以帮助我!谢谢!
