Linux Valgrind输出显示地址,而不是针对错误编码
我正在用我的程序运行Valgrind。它向我显示了两个错误,但只提到了针对它们的地址,甚至在调试构建中也没有提到实际的代码 你能帮我吗。帮助我理解它所说的内容以及如何到达错误的代码行 输出是Linux Valgrind输出显示地址,而不是针对错误编码,linux,centos,Linux,Centos,我正在用我的程序运行Valgrind。它向我显示了两个错误,但只提到了针对它们的地址,甚至在调试构建中也没有提到实际的代码 你能帮我吗。帮助我理解它所说的内容以及如何到达错误的代码行 输出是 ==23002== Memcheck, a memory error detector. ==23002== Copyright (C) 2002-2005, and GNU GPL'd, by Julian Seward et al. ==23002== Using LibVEX rev 1575

那个地址看起来是假的。忘记valgrind,启动以查找程序的错误位置。没有调试信息,因为指示的代码位于
ld-2.3.4.库中(这是动态链接器)
在我看来,您的可执行文件与损坏的动态库文件相链接(或者试图通过该机制加载非动态库的文件)。我看到您正在使用Valgrind 3.1.1。这是一个非常古老的版本。我建议你先考虑升级到3.5.0,再试试。新版本可能会为您提供更好的诊断。
