+ ;; 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>
