I have tried updating my local <nixpkgs> directory with 'nix-channel --update'.
No change; the full nix-instantiate command does not terminate. The git commit of <nixpkgs> (in /home/paul/.nix- defexpr/channels/nixpkgs/.version-suffix) is now 497e6d2. Also, if I remove '--strict' from the nix-instantiate command I get: <?xml version='1.0' encoding='utf-8'?> <expr> <derivation> <repeated /> </derivation> </expr> Terse##SELECTION_END##! but at least the process completes. I have noticed that the non-termination problem is not confined to the opencascage_oce package. If I try $ nix-instantiate --strict --eval --xml -A guile /home/paul/.nix- defexpr/channels/nixpkgs that does not terminate either. Best, Paul.
