;; Groff contains a Rube Goldberg-esque relocator for the
;; file "charset.alias".
;; 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>
;; for details.
