intra process communication not working

[christianrauch]

I am trying to get the intra process communication working.

I am just printing the address of published and subscribed messages in the opencv_cam_node and subscriber_node and I am getting different addresses, e.g.:

[opencv_cam]: Image message address [PUBLISH]:      0x7f5574002800
[image_subscriber]: Image message address [SUB]:    0x7f55740018e0
[opencv_cam]: Image message address [PUBLISH]:      0x7f5574002800
[image_subscriber]: Image message address [SUB]:    0x7f55740018e0
[opencv_cam]: Image message address [PUBLISH]:      0x7f5574002800
[image_subscriber]: Image message address [SUB]:    0x7f55740018e0

How do I enable the intra process communication such that the messages are shared between both nodes?

Interesting... I'm seeing the same thing on Foxy. Are you running Foxy?

I'll look into this.

Ah, I introduced that bug when I switched to using image_transport in dfc2099. I will back out that change in both branches.

I believe that this is fixed on both branches.
