New Comment:
At first note that -C means DO NOT chdir to the script's directory (it
is not clear from the report).
"-C" option has effect only for command-line usage by design.
In case PHP supports it in FastCGI mode (as requested), we will allow
incompatible behavior between FastCGI and other SAPIs, whish always do
chdir to script's directory. So scripts, which written in assumption
that this option work, won't work with other SAPIs. Also with this
option enabled, any chdir() in PHP script may break all the following
requests, because of invalid CWD expectation.
In your example (/usr/bin/php5-cgi -C -b 9876) "-C" just doesn't have
effect.

Description:
------------
The option -C "chdir to the script's directory" doesn't work when using
PHP as FASTCGI server.
Due to this issue a first request will work and a second identical
request will return "no input file specified"
Reproduce code:
---------------
$ strace -o strace.log /usr/bin/php5-cgi -C -b 9876
(run 2 identical requests)
$ grep "chdir\|index.php" strace.log
lstat64("/home/flgu/tmp/websvn/index.php", {st_mode=S_IFREG|0644,
st_size=1656, ...}) = 0
open("/home/flgu/tmp/websvn/index.php", O_RDONLY|O_LARGEFILE) = 7
chdir("/home/flgu/tmp/websvn") = 0
open("/home/flgu/tmp/websvn/websvn/index.php", O_RDONLY|O_LARGEFILE) =
-1 ENOENT (No such file or directory)
$
Note the double "websvn/websvn" in the second open.
You can use this cgi to test it (adapt it with your own path):
#!/bin/bash
export SCRIPT_FILENAME=${REQUEST_URI/\/~flgu\/fast.cgi\//}
/home/flgu/tmp/fcgi-2.4.0/cgi-fcgi/cgi-fcgi -bind -connect
localhost:9876
Expected result:
----------------
No chdir called and all request work
Actual result:
--------------
chdir called and only first request work
------------------------------------------------------------------------
