Now, this is very weird. I tried again with core-updates from today and
I’m back to the original problem in this bug report:

This is with the following commit:

$ git log --oneline -n1
c3e33474b965 (HEAD -> core-updates, origin/core-updates) gnu: biber: Update to 2.16.

I forgot to mention in my previous email which was the commit that worked.
It’s this one:

$ git log --oneline -n1
b15c3dd9b0e9 (HEAD) gnu: meson: Update to 0.59.0.

I just tested it again, and it does work if I revert back to it.

Thanks,
Thiago
