In reply to @jean-paul.:matrix.org
nope, Linux - but CircleCI

Just guessing, but is it because the kernel has IPv6 disabled via sysctl or perhaps even via kconfig?

Nix builds are sensitive to the host kernel.

@teoc:matrix.orgteo (they/he)I know the nixpkgs build of GHC edits the settings file, so I wanted to give y'all a heads up that the ghc-toolchain line of work is replacing the settings file, so it's likely that you'll need to make some changes here. See: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/1450013:48:05

@jean-paul.:matrix.orgjean-paul.Seems likely I guess. I don't know how to learn about CircleCI's kernel configuration. Annoyingly, zlib test suite also fails. Seems like that should be less sensitive to the kernel but 🤷14:45:54
@jean-paul.:matrix.orgjean-paul.I assume more folks than me want to use Nix on CircleCI14:46:10
@sternenseemann:systemli.orgsterniNow I'm scared about arithmetic regressions in 9.10.3… https://github.com/Bodigrim/arithmoi/issues/22314:58:30
@sternenseemann:systemli.orgsterniso far nothings else like that happened, though14:59:08
