Seg Fault Copying xtypes::DynamicData

[KyleStevenson3]

My first attempt to use this library failed. Here is a simple program that reproduces the failure.

#include <iostream>
#include <string>
#include "xtypes/xtypes.hpp"

using namespace eprosima;

xtypes::DynamicData getTestEnum()
{
    xtypes::EnumerationType<uint32_t> testEnum("TestEnum");
    testEnum.add_enumerator("item0");
    testEnum.add_enumerator("item1");
    testEnum.add_enumerator("item2");
    xtypes::DynamicData test(testEnum);
    std::cout << "Looks good here: " << test.to_string();

    xtypes::DynamicData test2(test);
    std::cout << "Here too: " << test2.to_string();
    return test;
}

int main()
{
    xtypes::DynamicData testData(getTestEnum());
    std::cout << "Seg Faults here: " << testData.to_string();
    return 0;
}

backtrace:
