FWIW, I think I fixed this particular error in the latest cargo (once #55999 lands, fixed by rust-lang/cargo#6292). I'm a little concerned because this coincidentally happened earlier today (rust-lang/cargo#6319), and these are the first occurrences I'm aware of since that test was added 7 months ago. Hopefully it will be fixed. Would you mind pinging me whenever you see a spurious cargo error? I've been trying to get cargo's tests to be more reliable, and any data is helpful. |
