1）导致错误的脚本是什么？

Question

我正在弄清楚是什么导致了Apache / PHP中的Segfault。

我如何找到：

＃1）导致错误的脚本是什么？

＃2）在

中发生错误的功能是什么

当我运行backtrace时，看起来它与init发生错误。当我进入框架时，我没有看到任何其他信息。

Answer 1

1）导致错误的脚本是什么？

堆栈跟踪中没有足够的信息告诉您。

您需要为libphp5.so安装调试符号，也可能为Apache安装调试符号。然后您可以找到该脚本。

如何安装调试符号的精确细节取决于您使用的操作系统和发行版，您也没有告诉我们。通常它类似于apt-get install php5-dbg，yum install php5-debug或类似的东西。

2）在
中发生错误的功能是什么

错误发生在object_properties_init()。

Apache / PHP Segfault无法使用gdb backtrace进行诊断
