When wget 1.21.2 is built to use OpenSSL, and OpenSSL was
built with the "no-ssl3 no-ssl3-method" options to disable
SSLv3 support, then wget core dumps when SSLv3 is requested:

% wget --secure-protocol=SSLv3 https://savannah.gnu.org/
--2022-07-12 17:32:01--  https://savannah.gnu.org/
OpenSSL: unimplemented 'secure-protocol' option value 2
Please report this issue to -email is unavailable-
Abort (core dumped)

This appears to be in ssl_init() in src/openssl.c - the
protocol versions unsupported by OpenSSL are #ifdef'ed
out of the switch statement altogether, falling down to
the default: case which prints an error and calls abort().

Since as bug 61416 notes, this option requests a minimum
version instead of an exact match, it would be better,
and seemingly more consistent with the gnutls version, if
the older protocol versions were always defined, and if
unsupported, the code instead fell through to the next
supported protocol release.
