I haven't done a bisect yet, but JuliaLang/julia#61016 looks suspicious.

@Keno @topolarity Is this a Julia bug, or a bug in Tar.jl?

[DilumAluthge]

Note that CI passed on Julia nightly several weeks ago, so this is a recent breakage.

[DilumAluthge]

I have an MWE, and I've filed upstream: JuliaLang/julia#61129
