To Reproduce
Steps to reproduce the behavior:

1. openrtm.orgで以下のテキストを貼り付け

<cpp>
#include <rtm/ByteDataStreamBase.h>
#include <rtm/idl/BasicDataTypeSkel.h>
#include <coil/Factory.h>
#include <rtm/Manager.h>

template <class DataType>
class TestSerializer : public RTC::ByteDataStream<DataType>
{
public:
    TestSerializer():m_buffer(NULL), m_length(0){};

    virtual void writeData(const unsigned char* buffer, unsigned long length)
    {
        delete m_buffer;
        m_buffer = new unsigned char[length];
        memcpy(m_buffer, buffer, length);
        m_length = length;
    }
    virtual void readData(unsigned char* buffer, unsigned long length) const
    {
        if (m_buffer)
        {
            memcpy(buffer, m_buffer, length);
        }
    }
    virtual unsigned long getDataLength() const
    {
        return m_length;
    };
    virtual bool serialize(const DataType& data)
    {
        delete m_buffer;
        m_buffer = new unsigned char[1];
        m_buffer[0] = static_cast<unsigned char>(data.data);
        m_length = 1;
        return true;
    };
    virtual bool deserialize(DataType& data)
    {
        if (m_buffer)
        {
            data.data = static_cast<long>(m_buffer[0])+1;
            return true;
        }
        return false;
    };
private:
    unsigned char* m_buffer;
    unsigned long m_length;

};

extern "C"
{
    DLL_EXPORT void TestSerializerInit(RTC::Manager* manager)
    {
        coil::GlobalFactory <::RTC::ByteDataStream<RTC::TimedLong>>::
            instance().addFactory("test",
                ::coil::Creator< ::RTC::ByteDataStream<RTC::TimedLong>,
                TestSerializer<RTC::TimedLong>>,
                ::coil::Destructor< ::RTC::ByteDataStream<RTC::TimedLong>,
                TestSerializer<RTC::TimedLong>>);
    };
