glibc中的dlopen错误

我正在尝试调试dlopen的一个问题，该问题在随机时间发生

我没有这个问题的复制机。基本上，当我在valgrind下运行一个可执行文件时，我偶尔会遇到这个错误

my_file.cxx

第342行：void*h=dlopen（“libstream.so”，RTLD_GLOBAL | RTLD_NOW）

我认为这是一个可能的原因

谢谢
偶尔出现错误肯定表明程序正在执行某些未定义的行为。发布的代码行是正确的，所以问题出在代码的其他地方。您是否能够用最少的程序重现这一点？我自己也看到过类似的错误。你安装了什么版本的ld？我没有复印机。ld版本2.20.51.0.2-5.42.el6 20100205I在执行跟踪的行号上出现了相同的错误。它是如何在程序集文件中出错的！它看起来确实像Glibc2.12中的一个bug
