Thanks Tom. So apparently I'm doing something wrong.

That's part of the finding, but not the whole finding.

It appears to me that the finding ends with:
==6566== Use of uninitialised value of size 8
==6566== at 0x533B449: _x86_64_AES_encrypt_compact (in
/usr/local/ssl/lib/libcrypto.so.1.0.0)
And starts with:
==6566== by 0x4103E7: DoStartupOpenSSL() (ac-openssl-1.cpp:494)
==6566== by 0x419504: main (main.cpp:69)
(Sorry to do it in reverse order. It seems natural because it follows
Valgrind's onscreen output).
Are you stating those are two different findings? If they are two
different findings, shouldn't there be two different:
==6566== by 0x4103E7: DoStartupOpenSSL() (ac-openssl-1.cpp:494)
==6566== by 0x419504: main (main.cpp:69)
