Previously, UBSAN errors might slip undetected (e.g. when 23678758 is in).
Look for x = -2147483648:

gcc:asan- https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945225#L1036
The builtin system test, which uses failing named -V, passed, tho error reports are somewhere in the output (look for main.c in the output):

system:gcc:asan- https://gitlab.isc.org/isc-projects/bind9/-/jobs/2945229
Validation jobs show that named -V with undefined behavior fails the test:
