No need for an update, as grep has done that for many years.

This is a configuration problem on the part of the memkind user. See:

Hello,

grep fails when using a certain malloc implementation (memkind) because of
its reliance on malloc returning 0 when zero size is passed to it. Memkind
returns NULL instead which according to authors [1] is one of the
acceptable values in malloc specification.

Can grep be updated to also support a NULL return value?

Thank you!
