--- Comment #3 from Xi Ruoyao <xry111 at gcc dot gnu.org> ---
-Wnull-dereference is known to give false warnings in many cases (the doc says
"the precision of the warnings depends on the optimization options used" and I
remember there are several recent PRs complaining it). So it's not suitable
for -Wall or -Wextra.
Maybe we can imply -Wnull-dereference with -Warray-bounds=2, but
-Warray-bounds=2 is not enabled by -Wall or -Wextra as well.
