- ;; Groff contains a Rube Goldberg-esque relocator for the

- ;; It tries to find the current executable using realpath,
- ;; a do-it-yourself search in $PATH and so on.
- ;; Furthermore, the routine that does the search is buggy
- ;; in that it doesn't handle error cases when they arise.
- ;; This causes preconv to segfault when trying to look up
- ;; the file "charset.alias" in the NULL location.
- ;; The "charset.alias" parser is a copy of gnulib's, and a
- ;; non-broken version of gnulib's "charset.alias" parser
- ;; is part of glibc's libcharset.
- ;; However, groff unconditionally uses their own
- ;; "charset.alias" parser, but then DOES NOT INSTALL the
- ;; file "charset.alias" when glibc is too new.
- ;; In Guix, our file "charset.alias" only contains an
- ;; obscure alias for ASCII and nothing else.
- ;; So just disable relocation and make the entire
- ;; "charset.alias" lookup fail.
- ;; See <https://debbugs.gnu.org/cgi/bugreport.cgi?bug=30785>
