CARLA 0.9.15 Docker container exits silently when using recorder in certain scenarios

[st3lzer]

Setup:

• official CARLA 0.9.15 image running inside Docker
• Client: carla_garage (local)
• GPU: NVIDIA A100
• No memory spikes observed during crash

Steps to Reproduce:

• Run CARLA 0.9.15 in a Docker container.
• Start a scenario with the client (e.g. BlockedIntersection or HighwayCutIn).
• Enable the recorder (/leaderboard_autopilot/leaderboard/leaderboard_evaluator_local.py, line 376: set argument=True).

Expected Behavior:

• Scenario runs with recording enabled.

Actual Behavior:

• As soon as the recorder starts, the Docker container exits without any error message.
• This only happens for some scenarios (BlockedIntersection, HighwayCutIn).
• Other scenarios (ParkingCutIn, Accident, ParkingCrossingPedestrian) run fine even with recorder.
• Without the recorder, all scenarios work as expected.

Notes:

• Ticking the simulation beforehand does not avoid the issue.
• The order of starting the recorder, loading the senario and running it does not matter.
• Appears to be more related to CARLA itself than carla_garage.
• No visible error logs in container, no GPU/CPU/SSD memory spikes.

I see the same behavior on CARLA 0.9.15 running natively. I do however get an error message, albeit essentially just a segfault. No carla_garage, i trigger this using the scenario runner.
