compiling diffutils 3.8 on RHEL 8.4 using a GCC 11.2.0 that I
built myself.  Perhaps the problem was not discovered earlier
because the attribute works with ‘free’ (which is what I was
seeing before on Fedora 34) but not with ‘rpl_free’ (seen on RHEL
8.4).  Anyway, the GCC manual says it shouldn’t work at all, so
don’t use it.
