Revision history [back]

I'm not sure what the status in galactic is, but while working with OpenRobotics on a project using Foxy, I was shown that your subscriber callbacks must use the unique_ptr instead of shared_ptr for intra-process comms to preserve the address. Try changing your callback signature to unique_ptr and see if you get the same result.
