###### 我想要达到的结果
通过分析源码，初步判断是在执行 keystore.gmin.so 中的函数时出的错，也就是日志中 ITEEKeyMaster 部分，但我没有 keystore.gmin.so 的源码，无法进一步分析。哪位能给予帮助？

另外，我之前提的一个问题，[Fatal signal 6 (SIGABRT), code -6 in tid 2860 (surfaceflinger) 该如何解决？](https://ask.csdn.net/questions/7624897?spm=1001.2014.3001.5505)，虽然没有人回答，但我摸索出来了解决方法，只是原提问已经被结题，无法写解决方法，只好写到这里：
那个报错中，有一条：dlopen failed: cannot locate symbol "ufoInitPlatform" referenced by "/system/vendor/lib/egl/libGLES_intel8.so"
原因是system中有两个 libskuwa.so，lib中一个，vendor/lib 中一个，只需要把 lib 中的删除就可以了。
