Additional info: curl.exe has the same behaviour.

        C:\phpdev\php55bad.x32>curl --version
        Auto configuration failed
        6960:error:0E065068:configuration file routines:STR_COPY:variable has no value:.\crypto\conf\conf_def.c:618:line 37

My laptop shows the version fine:

        C:\>curl --version
        curl 7.37.1 (i386-pc-win32) libcurl/7.37.1 OpenSSL/1.0.1h zlib/1.2.8 WinIDN libssh2/1.4.3
        Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
        Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM SPNEGO SSL SSPI libz

I have added curl.exe plus bin/lib/include to http://elijst.nl/php55bad.x32.zip which contains all the files involved. If you are a Windows user: unzip it, go to the php-dir and run either 'php -v' or 'curl --version'.

** [bugs:#1401] STR_COPY:variable has no value**
**Status:** open

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).
