The request is /xhprof/filename.php; that should be handled in this
location:

The combination of a regex location, alias, and try_files, probably does
not do what you want.

I suspect that the 404-with-no-error-log comes from this try_files line.

You could (temporarily) either remove the line, or replace it with

try_files "" =404;

in order to get through to the next stage of the configuration.

alias with variables (and possibly try_files, I don't recall) probably
leave some of these variables in a state you don't expect.

Your fastcgi server, when it receives repeated fastcgi params, will
probably only honour the first or the last one received. If you care,
test so that you know, or don't send repeat params (by editing the
fastcgi_params files, and only including it once).

So: what file-on-the-filesystem do you want your fastcgi server to
process?

What variable or variables in nginx make up exactly that name?

Put that in as SCRIPT_FILENAME.

(It may be that $document_root is all you need here.)

You can see what nginx sends by looking in the debug log; or by watching
the traffic going from nginx to the fastcgi server. Or maybe your fastcgi
server has its own logging.
