### Description ### Description We are using docker/docker-compose in a docker-in-docker context, but the problem should exists regardless of this type of usage. Locally (linux or MacOS ARM) a docker-in-docker image is executed and then `docker compose up` will be executed inside it. We are experiencing this problem on MacOS ARM but not on linux systems, but it is not clear if it depends on the base version of docker (see versions below). `docker compose up` returns `fatal error: concurrent map iteration and map write` <details> <summary>The complete stacktrace:</summary> fatal error: concurrent map iteration and map write goroutine 1 [running]:

Regardless docker-in-docker usage: 1) locally (linux or macos) `docker run --rm <docker-in-docker-image>` 2) docker-in-docker-image (linux arch) exec `docker compose up` ### Compose Version ```Text docker-compose-plugin inside docker-in-docker-image: - 5.1.3 --> works - 5.1.4 --> do not work ``` ### Docker Environment ```Text Docker version (Linux): 28.5.2 Docker version (ARM): 29.5.1 ``` ### Anything else? _No response_
