Opening the "php://stderr" stream and writing to it in FastCGI mode writes to the FCGI server's standard error, not the multiplexed request standard error stream.

Reproduce code:
$stderr = fopen("php://stderr", "w");
fputs($stderr, "fish soup is good for you");

Expected result:
This should log an error message to the server's error log when the script is running in a web server environment. (Note that error_log can't necessarily be used in this context, because it always appends a "\n" to anything you send, and is also affected by the configuration file.)

Actual result:
Under FastCGI mode, it doesn't log such a message, but instead writes it to the FGGI *server's* standard error stream, which isn't the same thing at all. The message should be written via the multiplexed FastCGI error stream, not to fd #2.

(See also a related bug, , which I've fixed.)

Basically this is simple but a bit messy to fix. In ext/standard/php_fopen_wrapper.c the php://stderr case (and possibly the other ones) need to be treated specially in the FastCGI case, defining new stream output operations for the FastCGI streams.
