On s390x, I get warnings like this when do_one_test is inlined with SIZE_MAX:
In function ‘do_one_test’,
inlined from ‘do_overflow_tests’ at tst-strlcat2.c:184:2:
tst-strlcat2.c:49:18: error: ‘strnlen’ specified bound [18446744073709550866, 18446744073709551615] exceeds maximum object size 9223372036854775807 [-Werror=stringop-overflow=]
49 | # define STRNLEN strnlen
| ^
tst-strlcat2.c:89:23: note: in expansion of macro ‘STRNLEN’
89 | size_t dst_length = STRNLEN (dst, n);
| ^~~~~~~
This patch just marks the do_one_test function as noinline as also done in test-strncat.c:
Fix stringop-overflow warning in test-strncat.
