第一次 使用valgrind 碰到问题

asang

测试程序是：
//----------------------------------
#include <stdio.h>
#include <stdlib.h>
int main()
{
        int *p, i, a;
        p = malloc(10*sizeof(int));
        p[10] = 1;
        p[11] = 1;
        a = p[11];
        free(p);
        return 0;
}
//---------------------------------------
然后
# gcc -g test.c -o test
# valgrind --tool=memcheck test

出来的信息是：
==5581== Memcheck, a memory error detector for x86-linux.
==5581== Copyright (C) 2002-2005, and GNU GPL'd, by Julian Seward et al.
==5581== Using valgrind-2.4.1, a program supervision framework for x86-linux.

==5581== For counts of detected errors, rerun with: -v
==5581== No malloc'd blocks -- no leaks are possible.


而且不管我用什么程序下去测试结果都是这样。。。


我的机子是c4 2.0 + fedora core4

你的问题是什么？

valgrind --tool=memcheck test <-- replace test with ./test

asang

谢谢大家的帮助，可以了。。

linuxsir就是好

呵呵，你还看得真仔细
