PVS-Studio warning V519 for OpenDDS

int
InfoRepoMulticastResponder::init(
  CORBA::ORB_ptr orb,
  const char *mcast_addr)
{
  ....
  } else {
    actual_mcast_addr =
      CORBA::string_alloc(static_cast<CORBA::ULong>(
        ACE_OS::strlen(mcast_addr)));

    actual_mcast_addr = mcast_addr;
  }
  ....
}

This suspicious code was found in OpenDDS project by PVS-Studio static code analyzer.
Warning message is:
V519 The 'actual_mcast_addr' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 89, 92. inforepomulticastresponder.cpp 92
