Crash when exporting rapidjson::Document as string

My code is like this:

rapidjson::Document doc;
doc.SetObject();

// insert some sub JsonObjects
rapidjson::Document subA;
if (!subA.Parse<0>(jsonStringA->c_str()).HasParseError()) {
    doc.AddMember("A", subA, doc.GetAllocator());
}

rapidjson::Document subB;
if (!subB.Parse<0>(jsonStringB->c_str()).HasParseError()) {
    doc.AddMember("B", subB, doc.GetAllocator());
}

// Export document as string
rapidjson::StringBuffer buf;
rapidjson::PrettyWriter<rapidjson::StringBuffer> writer(buf);
doc.Accept(writer);
buffer.GetString();

Fatal signal 6 (SIGABRT) produced after called buffer.GetString();

And the abort message is:

/document.h:1778: bool rapidjson::GenericValue<rapidjson::UTF8<char>, rapidjson::MemoryPoolAllocator<rapidjson::CrtAllocator> >::Accept(Handler &) const [Encoding = rapidjson::UTF8<char>, Allocator = rapidjson::MemoryPoolAllocator<rapidjson::CrtAllocator>, Handler = rapidjson::PrettyWriter<rapidjson::GenericStringBuffer<rapidjson::UTF8<char>, rapidjson::CrtAllocator>, rapidjson::UTF8<char>, rapidjson::UTF8<char>, rapidjson::CrtAllocator, 0>]: assertion "m->name.IsString()" failed'

I don't know what is wrong with my code.

And if i replace "rapidjson::Document subA" with "rapidjson::Document subA(doc.GetAllocator())", this issue appears to be resolved. But i don't know why.
