问题排查在源码中加log调试时，编译报错如下：

从这个错误打印中可以推断出SurfaceComposerClient的ALGE函数的调用trace如下：

system/core/liblog/include/log/log_main.h:242:52: note: expanded from macro 'ALOGE'
#define ALOGE(...) ((void)ALOG(LOG_ERROR, LOG_TAG, __VA_ARGS__))
                          ~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
system/core/liblog/include/log/log_main.h:308:67: note: expanded from macro 'ALOG'
#define ALOG(priority, tag, ...) LOG_PRI(ANDROID_##priority, tag, __VA_ARGS__)
                                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
system/core/liblog/include/log/log_main.h:72:69: note: expanded from macro 'LOG_PRI'
