gz_sim create subscribes to wrong topic

[muttistefano]

hi all,
i am on Ubuntu 22.04, Ros2 rolling, with ros_gz built from source.

I have noticed that the create node of ros_gz_sim has a weird behaviour.
when i run :
ros2 run ros_gz_sim create -topic sweepee_1/robot_description -name sweepee_2

the node subscribe to the topic "sweepee":
[INFO] [1702368228.031667490] [ros_gz_sim]: Waiting messages on topic [sweepee].

Whenever i change topic, the node subscribe only to the first 7 letters of the provided string.

ros2 run ros_gz_sim create -topic abcdefghil  
[INFO] [1702368480.765282089] [ros_gz_sim]: Requesting list of world names.  
[INFO] [1702368480.966820664] [ros_gz_sim]: Waiting messages on topic [abcdefg].  

Did anyone experience this ?
Thanks

I can't reproduce the issue, I tried from source and debs.

Can you provide more information ?

Debs also work fine in my case, but being on rolling i cannot use them.
Checking the source i can say that the FLAGS_topic variable seems to be the problem , but it is generated and read by the gflags library.
I indeed have the correct gflags library installed so i don't really know what's wrong.
I can try to reporoduce the problem in a new machine and check if it applies.
Thanks
