GCC 13 incorrectly thinks a call to free after a failed realloc is a
use after free.
lib/libcasper/services/cap_grp/cap_grp.c: In function 'group_resize':
lib/libcasper/services/cap_grp/cap_grp.c:65:17: error: pointer 'buf' may be used after 'realloc' [-Werror=use-after-free]
65 | free(buf);
| ^~~~~~~~~
lib/libcasper/services/cap_grp/cap_grp.c:63:19: note: call to 'realloc' here
63 | gbuffer = realloc(buf, gbufsize);
| ^~~~~~~~~~~~~~~~~~~~~~
