first test is fails, other tests is ok.

message.cpp:
...
message::~message()
{
if (m_data != nullptr) {
#ifdef NDEBUG
nn_freemsg(m_data);
#else
if (nn_freemsg(m_data) != 0) { // !!! THIS Fails !!!

}
}

Macro variable NDEBUG=1 was not defined in CMakeLists. Further, there was a buffer overflow due to std::strcpy appending a trailing \0 character. Does PR #21 solve this problem?
