#include<stdio.h>
main()
{
    float x=2;
    float y=4;
    printf("\n%d\n%f",x/y,x/y);
    printf("\n%f\n%d",x/y,x/y);
}

输出:

0 
0.000000
0.500000 
0

用gcc编译4.4.3程序退出时出错,代码为12

什么是错strcpy()的代码？

void process_filedata(char *filename)
{
  void* content;
  const char * buffer;
  char * temp;
  char * row;
  char * col;
  int lsize,buflen,tmp,num_scan; //num_scan - number of characters scanned
  int m=0,p=0,d=0,j=0; //m - machine, p - phase, d- delimiter, j - job

  FILE *file_pointer = fopen("machinetimesnew.csv","r");

  if(file_pointer == NULL)
  {
   error_flag =  print_error("Error opening file");

   if(error_flag) exit(1);
  }
  fseek(file_pointer, 0 ,SEEK_END);
  lsize = ftell(file_pointer);
  buflen = lsize;
  rewind(file_pointer);
 // content = (char*) malloc(sizeof(char)*lsize);
  fread(content,1,lsize,file_pointer);
  buffer = (const char*) content; …

typedef struct queue {

  int q[max];
  int qhead;
  int qrear;

} queue;


void init_queue(queue *QUEUE)
{
  QUEUE.qhead = 0;
  QUEUE.qrear = -1;
}
void enqueue(queue *QUEUE,int data)
{
  QUEUE.qrear++;
  QUEUE.q[QUEUE.qrear] = data;
}

int process_queue(queue *QUEUE)
{
  if(QUEUE.qhead > QUEUE.qrear) 
    return -1;
  else
    return QUEUE.q[QUEUE.qhead++];
}

我正在使用数组实现队列只是为了保持简单.用上面的代码搞错了？

程序接收信号SIGSEGV,分段故障.execute_jobs()中的0x08049795当前语言:auto; 目前asm

(gdb)信息符号0x08049795 execute_jobs + 22 in section .text

(gdb)ptype 0x08049795 type = int

如何获取发生错误的行号？
