I checked restarts with valgrind on latest 2.2.x and found this fixes:

The first one (ERR_free_strings) is fixed in 2.4.x and seems to be
backported in redhat's 2.2.* already (at least in
"httpd-2.2.15-56.el6_8.3.src.rpm").

The second one (sk_SSL_COMP_free) is nowhere, neither in httpd nor
redhat (AFAICT) releases.

The last and biggest one (EXTENDED_KEY_USAGE_free) is 2.2 code only
(2.4 not concerned), and seems to affect both httpd-2.x and redhat's.

I won't be able to verify how it affects the different openssl
versions (hence commit anything) in the next few days, just wanted to
notify before being away...

Regards,
Yann.
