FAILED TEST SUMMARY
---------------------------------------------------------------------
Bug #55646: textual input in openssl_csr_new() is not expected in UTF-8 [ext/openssl/tests/bug55646.phpt]
Bug #65729: CN_match gives false positive when wildcard is used [ext/openssl/tests/bug65729.phpt]

First failure is platform specific (OpenBSD /etc/ssl/openssl.cnf does not contain a v3_ca section
Second failure is kind of XFAIL lately

Can probably go into current 5.x branches too.

This patch is still relevant. Tested again on OpenBSD 5.6 and Linux with libressl-portable 2.1.3
