guild compile unknown character name ??

[Kovacsics Róbert]

Hi,

I have an odd error, which is (while compiling
https://gitlab.com/kavalogic-inc/inspekt3d/)

What makes it odd, is that when I set the GUILE_*_PATHs and execute
the `/nix/.../guild compile` command, it compiles fine. It's the same
guild executable, the same files, so not sure why it's not working
inside a nix builder, but working outside it. Mainly asking if anyone
has a way I could try to debug it (guild/guile side) or any intuition
of why it might not be happy. From the nix side, this guild compile is
being ran in a sandbox, perhaps it cannot access some file (and thus
gets an EOF or something it cannot access), and the error message is
just unhelpful?

Here is the build log, with strace on the guild command, it seems to
be able to find the "libfive-guile.so" from the load-extension

Thanks,
Robert
