Demangle not working on ebpf with rust code

[Sh4d1]

Hello! I'm trying to setup ebpf profiles. Currently, I'm running grafana alloy with the following configuration:

discovery.kubernetes "all_pods" {
  role = "pod"
  selectors {
    field = "spec.nodeName=" + sys.env("HOSTNAME")
    role = "pod"
  }
}

discovery.relabel "local_pods" {
  targets = discovery.kubernetes.all_pods.targets
  rule {
    action = "drop"
    regex = "Succeeded|Failed"
    source_labels = ["__meta_kubernetes_pod_phase"]
  }
  rule {
    action = "replace"
    regex = "(.*)@(.*)"
    replacement = "ebpf/${1}/${2}"
    separator = "@"
    source_labels = ["__meta_kubernetes_namespace", "__meta_kubernetes_pod_container_name"]
    target_label = "service_name"
  }
}
pyroscope.ebpf "local_pods" {
  forward_to = [ pyroscope.write.endpoint.receiver ]
  targets = discovery.relabel.local_pods.output
  
  demangle = "full"
  python_enabled = false
}

pyroscope.write "endpoint" {
  endpoint {
    url = "http://pyroscope.monitoring:4040"
  }
}

This works, however my function names are still mangled, as you can see in the image:

I'm running alloy 1.7.1 and pyroscope 0.12, both on kubernetes.
Posting it here since it seems the demangle happens in a package here. Let me know if you need anything else!
