--- Comment #1 from Sam James <sam at gentoo dot org> ---
Fixed in
https://sourceware.org/git/?p=elfutils.git;a=commit;h=ae580d48278b9924da7503886b37be34378e1b04,
just needs a new release before 14 is out (or we get mjw to change his mind on
werror for releases finally :p)

commit ae580d48278b9924da7503886b37be34378e1b04

    tests: fix build against upcoming `gcc-14`
(`-Werror=calloc-transposed-args`)

    `gcc-14` added a new `-Wcalloc-transposed-args` warning recently. It
    detected minor infelicity in `calloc()` API usage in `elfutils`:

        elfstrmerge.c: In function 'main':
        elfstrmerge.c:450:32: error:
          'calloc' sizes specified with 'sizeof' in the earlier argument and
not in the later argument [-Werror=calloc-transposed-args]
          450 |   newscnbufs = calloc (sizeof (void *), newshnums);
              |                                ^~~~
        elfstrmerge.c:450:32: note: earlier argument should specify number of
elements, later size of each element
