无法关闭文件?? [英] can't close a file??

问题描述

当我编译程序时，我得到了一个分段错误如下：


程序接收信号SIGSEGV，分段错误。
来自/lib/i686/libc.so.6的_int_free（）中的
0x42074bd0
来自/ lib / i686 /的_int_free（）中的
＃0 0x42074bd0 libc.so.6

＃1 0x42075a5c in free（）from /lib/i686/libc.so.6

＃2 0x4206293c in fclose @@ GLIBC_2.1（ ）来自/lib/i686/libc.so.6

＃3 0x08049a76 in getNewDeploy（deploy = 0x804b450）at redeploy.c：839

＃4 0x08049867 in generate_table（ dif = 0xbfffde80）在redeploy.c：725

＃5 0x08048786 in main（）at redeploy.c：63

＃6 0x420158f7 in __libc_start_main（）from / lib / i686 / libc.so.6

错误是由函数fclose引起的。在程序中，我打开一个文件，

从中读取一些数据，然后关闭它。我刚刚使用gdb检查过。

数据可以正确读取。然而，当谈到fclose时，出现了一个段错误

。可能某人给我一些可能导致fclose失败的想法？谢谢

提前。


最好。

Hi,

When i compiled a program, i got a segmentation fault as follows:

Program received signal SIGSEGV, Segmentation fault.
0x42074bd0 in _int_free () from /lib/i686/libc.so.6

#0 0x42074bd0 in _int_free () from /lib/i686/libc.so.6
#1 0x42075a5c in free () from /lib/i686/libc.so.6
#2 0x4206293c in fclose@@GLIBC_2.1 () from /lib/i686/libc.so.6

#5 0x08048786 in main () at redeploy.c:63
#6 0x420158f7 in __libc_start_main () from /lib/i686/libc.so.6
The error was caused by function fclose. In the program, i open a file,
read some data from it, then close it. I just checked using gdb. The
data can be read correctly. however when it comes to fclose, a seg fault
appears. Could sb. give me some ideas what may cause fclose fail? Thanks
in advance.

Best.

极不可能。更可能的是，你的代码出现了问题

。


在程序中，我打开一个文件，


您是否检查了''fopen（）''的返回值？

从中读取一些数据，


您是否检查过您的读数成功/失败的操作？

然后关闭它。我刚刚使用gdb检查过。

The error was caused by function fclose.
Highly unlikely. More likely, there''s something wrong
with your code.

In the program, i open a file,
Did you check the return value from ''fopen()''?
read some data from it,
Did you check your read operations for success/failure?
then close it. I just checked using gdb. The
data can be read correctly. however when it comes to fclose, a seg fault
appears. Could sb. give me some ideas what may cause fclose fail? Thanks
in advance.

你在第47行有一个错误。（也就是我们怎么知道没有

看到任何代码？）。

You have a bug on line 47. (I.e. how the *** can we know without
seeing any code?).
