No, but 1.0.2g in default builds omits three previously defined functions,
SSLv2_method(),
SSLv2_client_method(),
SSLv2_server_method().
on platforms where symbol (function name) resolution is not "lazy"
(delayed to first use), programs that can but don't in practice
use SSLv2 may not start when the library no longer provides these
functions.

The commit above restores the symbols. If you could build that
version (checkout from git, or apply the patch) and confirm whether
the issue is resolved, that would be great.

Retain SSLv2 methods as functions that return NULL
This improves ABI compatibility when symbol resolution is not lazy.
