Error in stale_dups[i:end_i] <- wh : replacement has length zero

[HenrikBengtsson]

revdepcheck::cran_revdeps() fails for some evercran dates, e.g.

$ R --vanilla
R version 4.5.1 (2025-06-13) -- "Great Square Root"
...
options(repos = "https://evercran.r-pkg.org/2024/06/14")
db <- revdepcheck::cran_revdeps("parallel")

gives:

Sorry, I should clarify that this is only the case for some evercran dates. It works for, say, 2024-06-10;

options(repos = "https://evercran.r-pkg.org/2024/06/10")
db <- revdepcheck::cran_revdeps("parallel")
