Startup access to uuid breaks package load and hence install

[eddelbuettel]

Describe the bug

The package cannot install (or load, hence breaking install of reverse dependencies, here mlr3) as it dies on *** buffer overflow detected ***: terminated

Reproduce example

At least on my system:

$ Rscript -e 'install.packages("future")'

There is clearly something else going on but I do not know what. Ubuntu 24.04, very vanilla, lots of other packages installed, no unusual environment variables.

Expected behavior

Being able to do library(future)

By trial and error I was able to have it install with this diff which avoids the buffer overflow:

Ah never mind it was of course ... all me. We are doing current work on digest and my local dev version borked it.

With digest from CRAN, future installs fine (as one would expect) and then so does mlr3. All good.
