query.c:5430:16: runtime error: load of value 190, which is not a valid value for type '_Bool'

This was originally reported in https://gitlab.isc.org/isc-private/bind-qa/-/issues/38#note_189030.

When AddressSanitizer constraint from libns unit tests are dropped, query_test produces runtime error:

[==========] Running 4 test(s).
[ RUN      ] ns__query_sfcache_test
[       OK ] ns__query_sfcache_test
[ RUN      ] ns__query_start_test

[       OK ] ns__query_hookasync_e2e_test
[==========] 4 test(s) run.

This is what @michal suggests at https://gitlab.isc.org/isc-private/bind-qa/-/issues/38#note_189274:

This error is a nice catch by ASAN because 190 is 0xbe in hex. The error is triggered because the checknames field of struct dns_view is not initialized by dns_view_create(). This is a workaround for lib/ns/tests/query_test.c:

diff --git a/lib/ns/tests/query_test.c b/lib/ns/tests/query_test.c

+	qctx->client->view->checknames = true;
 	result = ns_test_serve_zone("foo", "testdata/query/foo.db",
 				    qctx->client->view);
 	INSIST(result == ISC_R_SUCCESS);

However, I would also consider an alternative approach: adding view->checknames = false; to dns_view_create(). I have not tested that, though. Note that the default 0xbe value means that a check for view->checknames (which is supposed to be a boolean) would evaluate to true rather than false.
