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!
