Embedded nul in string

If I install the version of pak from CRAN, I sometimes get issues such as the following:

> pak::pkg_install("curl")

However, if I switch to the prebuild binary version, there are no issues.

Actually it's now failing under the pre-built version as well now.

I'll have a bit of a poke around as it might be an issue with my system.

This is coming from utils::untar() when it is trying to uncompress the source R package file. First I would try to clean the cache to make sure it is not a corrupt package file:

pak::cache_clean()

This is the correct hash of the curl 6.1.0 source file:

pak::cache_list(package = "curl", platform = "source")[, c("version", "sha256")]

# A data frame: 1 × 2
  version sha256
  <chr>   <chr>
1 6.1.0   81d45525057fe21be3d57071e65032114c9014392454dd40ff32ca5e5ae2c539
