Error: Reference to undefined global `Virtual_atomic’

Same error with a plain toplevel, but more details. # #require "domainslib";;0~alpha1/lib/lockfree/lockfree.cma: loaded Error: Reference to undefined global `Virtual_atomic'

In the interests of not breaking everyone’s toplevels just before OCaml 5.0 is released, I’ve marked lockfree.0.3.0 as unavailable in the opam repository. If you opam update shortly, it should recompile utop with the older lockfree.0.2.0 and things should work again. …
