//! Verify that we correctly handle fn pointer provenance in MIR optimizations.
//! By asking to inline `static_fnptr::bar`, we have two copies of `static_fnptr::foo`, one in the
//! auxiliary crate and one in the local crate CGU.

This seems to rely on foo being automatically marked as inline? Does inline(never) on foo make the issue go away?

If yes it'd be better to mark it as inline explicitly to avoid rely on the auto-inline heuristic.
