Interestingly, Viktor had just added some explicit NULL assignments
after memset-to-zero a few days ago in
a0724ef1c9b9e2090bdd96b784f492b6a3952957.  It is permitted for the NULL
pointer to have a representation other than all-zeros, but such
platforms are rare, and are explicitly excluded from the supported
platforms list for, e.g., MIT krb5.  Does openssl want to try to support
such platforms?
