Verdict: official glibc tarball does not run on Alpine as-is; gcompat
is not a credible fix for something Blender-sized (per gcompat's own
docs and one concrete failed community attempt). A musl-native
alternative exists (Alpine community's blender-headless package,
5.2.0-r0) but only on the edge branch, not a stable release — a real
argument against Alpine for this pipeline's pinned-version needs.
