请问 如何用valgrind 检查后台服务进程的内存使用情况? 谢谢!

有个比较诡异的现象，一段代码，老很快就core了，但是加了valgrind启动，运行了很久都不core。 我对valgrind不熟悉，大家有遇到类似的现象吗？

有时候运行valgrind会产生vgcore.pidxxxx文件 这种文件怎样去调试 用gdb调试普通core的办法不大行 打印不出调用栈，定位不了错误信息

[code]#include #include void *thread_1(void *argc) { pthread_self(); } int main() { pthread_t tid; pthread_create(&tid , NULL , thread_1 , NULL); } ~ ~ ~[/code] 运行valgrind --tool=memcheck --leak-check=yes --show-reachable=yes ./test [code]ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 21 from 1) ==10237== malloc/free: in use at exit: 144 bytes in 1 b...

我用 valgrind --tool=memcheck --leak-check=yes --show-reachable=yes ./server 运行程序 输出 ==26420== Memcheck, a memory error detector. ==26420== Copyright (C) 2002-2006, and GNU GPL'd, by Julian Seward et al. ==26420== Using LibVEX rev 1606, a library for dynamic binary translation. ==26420== Copyright (C) 2004-2006, and GNU GPL'd, by OpenWorks LLP. ==26420== Using valgrind-3.2.0, a dynamic binar...

我的系统是红帽企业 Linux ES 4, 用whereis命令发现系统已内置了valgrind, 但版本是v3.2.0, 现在想升级到v3.2.3 (已经下载了 valgrind-3.2.3.tar.bz2 包), 怎么做? 直接安装就可以么?

configure: error: /bin/sh ./config.sub make failed 就失败了。 晕啊！哪位兄弟知道的，怎么解决。

用valgrind检查内存泄漏， 如下: 2,448 bytes in 17 blocks are possibly lost in loss record 34 of 37 ==12744== at 0x4023492: calloc (in /usr/lib/valgrind/x86-linux/vgpreload_memcheck.so) ==12744== by 0x4010D38: (within /lib/ld-2.8.so) ==12744== by 0x4010DFB: _dl_allocate_tls (in /lib/ld-2.8.so) ==12744== by 0x40409D9: pthread_create@@GLIBC_2.1 (in /lib/libpthread-2.8.so) ==12744== by 0...
