【问题描述】：
protobuf 版本是 3.0.0。在某些设备（比如 Android 6）中，这个问题总是会发生；在某些设备（例如 Android 5.x）中，当应用进入后台模式时会出现此问题。
我正在调用以下方法：
bool ParseFromString(const string& data);
这可能在内部调用bool ParseFromArray(const void* data, int size)。堆栈跟踪：

显然如箭头所示，它在google::protobuf::internal::WireFormatLite::ReadBytes(...) 处崩溃。这个问题已经在this thread 中讨论过，用户通过将 VS2005 升级到 VS2008 来修复它。但是我们在 Android 中运行它。
我也参考了以下帖子无济于事：
- Android application crashes because of protobuf
- Crash when parsing protobuf message containing a string using C++ and Android NDK
- zeromq with protobuf segmentation fault while parsing in c++
- Generated Protobuf code crashes application
感谢任何详细的帮助，因为我是使用 Android 构建 protobuf 库的新手。
