Hi Christopher,
the error happens during the phase “patch-unix-tool-paths”. Looking at
the package definition I see that all files ending on “.lisp” or “.sh”
are to be patched.
The backtrace shows us that the null characters are encountered in the
file “./tests/data/compile-file-pos-utf16be.lisp”.
I met a similar problem in another package (but I don’t remember which
it was). It seems that Guile’s regular expression matching fails when
it encounters ASCII 0. (I’m not sure why this is and I don’t know if
there’s a good workaround for this behaviour. Maybe we could ask #guile
on IRC.)
To get past this issue for now you could ...erm, ...delete the file
(when nobody is looking). If this fixes your problem a better approach
might be to explicitly exclude this file from the list of files to be
patched. This would require modification of this expression:
(find-files "." "\\.(lisp|sh)$")
Hope this helps!
