Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

$ curl -L https://github.com/prefix-dev/pixi/releases/download/v0.40.1/pixi-aarch64-unknown-linux-musl.tar.gz -o pixi.tgz
$ tar xf pixi.tgz
./pixi info

Issue description

This works fine with the previous build (0.40.0), which you can test making a substitution on the above instructions.

Potential solution

I've seen this in the uv binary shipped with conda-forge a couple of weeks ago. This has been also reported in the uv repository itself. The solution is rather simple, but needs to be added to the build scripts:

# Use jemalloc on linux-aarch64 and linux-ppc64le
if [[ "${target_platform}" == "linux-aarch64" || "${target_platform}" == "linux-ppc64le" ]]; then
  export JEMALLOC_SYS_WITH_LG_PAGE=16
fi

As of now pixi 0.40.1 on raspberry PI is not usable.

Expected behavior

Well, it should not crash 😆

I confirm version 0.40.2 is still affected by the same issue.

Thank you I'll take a look!
