  "message": "Freeze libraries to link before interning them.\n\nOtherwise, Blaze is susceptible to a race condition:\n\n1. Node A creates a list [\"x\"] and interns it\n2. Node B creates the same list [\"x\"] and interns it; it gets back a still mutable reference to the list created by node A\n3. Node B finishes, freezes its Starlark data structures and puts a reference to the list (which is secretly created by Node A) into a provider\n4. Node A adds \"y\" to the list\n5. Now Node C (depending on Node B) will observe the values of the list as [\"x\", \"y\"], even though that\u0027s totally not what Node B intended\n\nRELNOTES: None.\nPiperOrigin-RevId: 947612088\nChange-Id: I98fd1dadaaa0e0677577627ce63039599a72f66b\n",
