I was using GCC 14, however GCC 15 shows the same error:

In file included from bench-calloc-tcache.c:22:
bench-malloc-tcache.c: In function ‘do_benchmark’:
bench-malloc-tcache.c:96:12: error: pointer ‘elem’ used after ‘free’ [-Werror=use-after-free]
   96 |   *iters = malloc_benchmark_loop (elem);
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
bench-malloc-tcache.c:93:3: note: call to ‘free’ here
   93 |   free (elem);
      |   ^~~~~~~~~~~

Cheers,
Wilco
