Subject: Fix dict traversal returning NULL + key_size
X-Git-Url: https://git.ljiriste.work/?a=commitdiff_plain;h=addf28c14063c052d44dce1b6bd0ddc532497163;p=Libft.git

Fix dict traversal returning NULL + key_size

Because I have done no checking the returned NULL has been increased by
the key size and then would not register as NULL anymore.
