因此，首先我想说，我们已经连续4天研究这个问题，试图找出解决方案，但一直无法找到有效的答案。Xdebug分割错误
因此大约两周前，我们决定作为一家公司，现在是时候将我们的ubuntu web服务器升级到最新版本。所以我们继续升级，一切似乎都很顺利。直到我们试图使用xdebug来调试一个magento应用程序。
我们在以前版本的ubuntu上安装了xdebug，并且能够在没有任何问题的情况下完美地进行调试。每次我们尝试调试Magento网站时，我们现在都会出现分段错误错误。
您可以在下面的pastebin链接中看到我们的php.ini文件。我们也有一个本地的PHP控装置，带下列选项： xdebug.remote_host = localcomputerip xdebug.remote_port = 9001
PHP ini文件http://pastebin.com/UYLviByW
我们使用调试Visual Studio和NetBeans的在我们的环境。当我们开始调试会话时，它实际上最初在index.php文件中破坏。我们可以逐步完成该过程一段时间，直到应用程序的随机点。正如你看到一个核心转储发生

#91 0x00007f6758041e36 in main (argc=3, argv=0x7fff4adf3968) at main.c:777现在我都没有Linux专家，但这个有我困惑。我们已经尝试了以下几点： 试过xdebug版本2.2.3 - 2.2.6 卸载Ioncube 卸载Zend OPCache 关闭PHP缓冲区输出。 试了从无到有 重新编译Apache的 重新安装PHP 5.5重新安装Xdebug的 打开的端口在重新启动Web服务器
现在让我来解释一下我们的服务器设置的iptables 。这是我们本地网络的内部开发服务器。它安装了Ubuntu 14.04。内部和外部的所有防火墙端口都可以正确打开端口。这是在电源服务器上运行的虚拟机。
我的眼睛开始流血，因为我们正在掌握我的linux知识。这个问题也有一个很大的问题。我们在同一台服务器上安装了WordPress网站。有时我们实际上能够通过整个WordPress会话进行调试。其他时候，我们无法调试wordpress并遇到同样的问题。这使得问题变得更加诡异。
任何人都可能对我所遇到的问题有任何帮助，那将是惊人的。我现在对任何东西都很开放，因为这是我们的开发服务器。
如果有任何其他信息需要您帮助解决此问题，请告诉我。现在我们回到var_dump和print_r调试方法。
这么长的问题。尽管我不知道如何解决这个问题，但从我的经验来看，当你开始通过与某人交谈或写下来描述它时，解决方案就会出现。放松。 – D3Hunter
我很欣赏这个反馈。正如我所说，这超出了我的知识障碍，并且正在寻求一些帮助。我在工作中与其他同事讨论过这个问题，它真的超出了我们综合知识的范围。再次，我感谢任何有用的人提供的。 –
