Description:
------------
The SSL stream context's "cafile" option expects the name of a file. When this name is not a "normal" filename but, for instance, "phar://phar-alias/ca.pem" I get the following error

  Unable to set verify locations `phar://phpunit-3.8-gb5ac7cc.phar/ca.pem'

This looks to me like stream wrappers are not applied in this context.

This makes it impossible to ship a PHAR that contains a CA file and use that to verify the peer (without copying it from the PHAR to a temporary file).
