Description:
------------
If you call mcrypt_create_iv with either the MCRYPT_DEV_RANDOM or 
MCRYPT_DEV_URANDOM constants, and it cannot generate enough data, it issues an 
E_ERROR fatal error.  However, on linux when the same situation it will just 
issue 
an E_WARNING.

I suggest that it should be changed from an E_ERROR to an E_WARNING on Windows 
(as 
it certainly is recoverable).

See:

http://svn.php.net/viewvc/php/php-src/branches/PHP_5_4/ext/mcrypt/mcrypt.c?
revision=311033&view=markup

Specifically lines 1397 and 1422
