I have an Android application implemented with help of cocos2d-x engine.
I linked protobuf library to the project and trying to SerializeToStrint() one proto-object:
ProtoMessage message;
message.set_app_id(1111);
message.set_hardware_id("test string");
std::string str;
message.SerializeToString(&str);
That’s builds fine, but when I trying to start application logcat send me next log:

Please can anybody explain me causes of this?
UPDATE
But if I initialize string in such way:
ProtoMessage message;
message.set_app_id(1111);
message.set_hardware_id("test string");
std::string str;
str = "test";
message.SerializeToString(&str);
everything is fine and proto serializes normally
UPDATED I added a add2line result below

UPDATE
and the most annoying problem I can’t parse proto-object without string fields initialization.
//str - serializing protobuf object
RegistrationRequest request;
request.ParseFromString(str);
Error!
When I compile that in test application on my desctop machine everything is fine.
But If I compile via cocos2d-x script (ndk.r7) application crashes on mobile device
Make sure libprotobuf.so and libpromowall.so are built with the same STL implementation: either stlport_shared or gnustl_shared.
