I filed an issue with OpenSSL but they seem to think the current behavior is fine: http://rt.openssl.org/Ticket/Display.html?id=3488&user=guest&pass=guest

** [bugs:#1401] OPENSSL_config causes app to exit with bad conf file**
**Status:** open
**Labels:** openssl VC9 VC11 Windows 2008

I got this error after upgrading to libcurl 7.37.1 and compiling php_curl.dll with it on Windows
	C:\phpdev\php55nts.x32>php -v
	Auto configuration failed
	7140:error:0E065068:configuration file routines:STR_COPY:variable has no value:.
	\crypto\conf\conf_def.c:618:line 37
To analyze what went wrong, I went back to libcurl 7.37.0 and applied the openssl patches since that release:
7.37.0 unpatched: OK
7.37.0 with the 'Fix uninitialized variable use in NPN callback': still OK
7.37.0 with the additional 'call OPENSSL_config for initing engines' patch: error
So this commit broke it on my server:
https://github.com/bagder/curl/commit/c50ce859187cabecee5470a95a51c35bf73d3c47
OS: Windows 2008 R2
OpenSSL 1.0.1h
PHP-versions: 5.3-29-dev, 5.4.31, 5.5.15
So it happened both with PHP compiled with VC9 (5.3, 5.4) as with PHP compiled with VC11 (5.5).
Other point that is relevant: it only happened on the production server. I could not reproduce it on the developmet server, which runs Windows 2008 R2 as well. And also on my laptop with Windows 7 it did not happen.
Furthermore: it went wrong with every php-extension that used libcurl (php_http.dll for instance).
