using Docker, I have a segmentation fault when using gz topic --echo -t /bar if the publisher is publisher_custom_msg. However, in the documentation, it is written : "You can modify any of the publisher examples to add this option.".

I mean, the publisher works well with remapping even with custom msg but I guess I need to specify to "gz" where custom messages are ?

Some screenshots for other tests :
