我可以做的valgrind忽视的glibc库？ [英] Can I make valgrind ignore glibc libraries?

问题描述

是否有可能告诉Valgrind的忽略一些的库？
具体的glibc库。

Is it possible to tell valgrind to ignore some set of libraries? Specifically glibc libraries..

实际的问题：
我有一个运行在正常执行一些罚款code。无泄漏等。

Actual Problem: I have some code that runs fine in normal execution. No leaks etc.

当我试图通过Valgrind的运行它，我得到核心转储和程序重新启动/停止。

When I try to run it through valgrind, I get core dumps and program restarts/stops.

核心通常指向glibc的功能（通常fseek的，互斥等）。
据我所知，可能有一些问题不兼容的glibc / Valgrind的版本。

Core usually points to glibc functions (usually fseek, mutex etc). I understand that there might be some issue with incompatible glibc / valgrind version.

我尝试过各种版本的Valgrind的和glibc的版本，但没有运气。
有什么建议么？

I tried various valgrind releases and glibc versions but no luck. Any suggestions?

推荐答案

这可能不回答你的问题，但会提供你如何燮preSS某些错误的细节（这其他人提到，但有就不详细说明了）：

This probably doesn't answer your question, but will provide you the specifics of how to suppress certain errors (which others have alluded to but have not described in detail):

首先，运行的valgrind 如下：

 valgrind --gen-suppressions=all --log-file=valgrind.out ./a.out

现在输出文件 valgrind.out 将包含一些自动生成的SUP pression块这样的：

Now the output file valgrind.out will contain some automatically-generated suppression blocks like the following:

{
   stupid sendmsg bug: http://sourceware.org/bugzilla/show_bug.cgi?id=14687
   Memcheck:Param
   sendmsg(mmsg[0].msg_hdr)
   fun:sendmmsg
   obj:/usr/lib/libresolv-2.17.so
   fun:__libc_res_nquery
   obj:/usr/lib/libresolv-2.17.so
   fun:__libc_res_nsearch
   fun:_nss_dns_gethostbyname4_r
   fun:gaih_inet
   fun:getaddrinfo
   fun:get_socket_fd
   fun:main
}

在哪里愚蠢SENDMSG虫和链接是我添加引用此块的名称。现在，该块保存到 sendmsg.supp ，并告诉的valgrind 关于下一次运行该文件：

Where "stupid sendmsg bug" and the link are the name that I added to refer to this block. Now, save that block to sendmsg.supp and tell valgrind about that file on the next run:

valgrind --log-file=valgrind --suppressions=sendmsg.supp ./a.out

和的valgrind 将慷慨地忽略那个愚蠢的错误上游

And valgrind will graciously ignore that stupid upstream bug.
