To Reproduce
accidental occurance
eventually crash
Expected behavior
what should i do, this is my app or json or libc problem?

Desktop (please complete the following information):
centos 7
intel cpu
** mycode

    Json::Value data;
    data = Json::objectValue;
    if (type == "json") {
        Json::Value result = Json::arrayValue;
        for (auto i : myResult) {
            result.append(i);
        }
        data["json"].append(result);
    } else {
        std::string result;
        for (auto i : myResult) {
            result += std::to_string(i) + " ";
        }
        data["txt"].append(result);
    }

No source file or test is named. Start with the supplied stack trace and the shown Json::Value construction on CentOS 7, then reduce the accidental crash to a reproducible case. Done means establishing whether the fault is in the application, jsoncpp, or libc and documenting a minimal reproducer or actionable diagnosis.
