Is it possible to clarify what "the result would be incomplete" mean?
(1) The size of coredump file becomes smaller than it should be, and
data in reaped pages is not included into the file.
(2) The size of coredump file does not change, and data in reaped pages
is included into the file as NUL byte.
(3) The size of coredump file does not change, and data in reaped pages
is included into the file as-is (i.e. information leak security risk).
