Description:
------------
the libeay32.dll (OpenSSL) appears to be a dependency of several other PHP modules, postgres, cURL etc..   It accesses a non existent drive D:, which then causes a dialog to appear, and the PHP script blocks until it's clicked.


Test script:
---------------
affects PHP even before a script runs.
php --version  even triggers it.

Expected result:
----------------
don't access drives on my machine that don't even exist!

Actual result:
--------------
accesses non existent drives, causing the running of PHP to block.

Thanks for the report. Have you tried something like process monitor to check what exactly is looked for on drive d:? Just a guess, it might be the openssl.cnf path, but have to check.

Which Windows do you use? I've just tried on a machine with only disk c: and no popups, no hanging (but if the config path is wrong, should be fixed anyway).

And, btw - why is this security? It's still RC. If there's no particular reason, probably should be set to a normal bug.

Thanks.

Ah, Stas already set it to the bug, we just had a race condition :)

@bob could you please try the env vars described here http://php.net/manual/en/openssl.installation.php for configuration? Like OPENSSL_CONF, that should override the default paths anyway.

Thanks.

Sounds like bug #68312, which @bob also commented on today.

Yes, you're right - this one is the duplicate. It is the same issue, lets handle it there.

Thanks.
