I don't have this test in fron of me but in general, some tests use
plain assert() to verify that the test itself is sane (e.g., that
pointers that must not be null are in fact non null). These should
probably just use the RW_ASSERT() macro (which does the same thing
as assert but independently of NDEBUG and can't be turned off).

Other tests might use the (old) RW_ASSERT() or RW_ASSERT_FILE() macros
to assert other types of test preconditions that are unrelated to what
is being tested (e.g., that the localedef utility successfully produced
a locale). These should be replaced by calls to the rw_error() function
when the test can continue processing after this error, or by rw_fatal()
when the error is not recoverable. The latter should only be used in
extreme cases since it makes the whole test exit at the point of the
