Symbols not found for rust application

[Erigara]

I've faced a problem that symbols are not present for my rust application.

I used this tutorial to deploy parca in my minikube.

When i used rust example from parca-demo everything worked just fine.

I checked that i compile my rust application with frame pointers and debug info enabled.

[profile.profiling]
inherits = "release"
debug = true
rustflags = ["-C", "force-frame-pointers=on"]

Here is log a message i get on parca server for binary build-id:

level=debug name=parca ts=2024-01-11T07:56:41.665588168Z caller=symbolizer.go:299 component=symbolizer buildid=db0e60c38be43955 msg="storage symbolization request failed" err="fetching metadata: debuginfo metadata not found"

And on the agent:

level=debug name=parca-agent ts=2024-01-11T07:54:57.463890053Z caller=pool.go:172 msg="evicting object file" key="{path:/usr/local/bin/iroha buildID:db0e60c38be43955 modtime:{wall:0 ext:63839531244 loc:0x3ebc920}}"

When i use perf to profile the same image on docker, everything works just fine.

@brancz do you maybe have a rough understanding of what's wrong? I'd need to dive deeper into the topic.

Might be relevant here parca-dev/parca-agent/issues/1658 i will try to compile our project with libc instead of musl and report results.

Indeed the problem was in musl, so i guess this should be closed in favor of parca-agent issue.
