Hi, the 5.4RC3 and the trunk have this bug.
After trace the core.
I found the SG(rfc1867_uploaded_files) did't set to NULL when sapi deactive.
when trying to free the SG(rfc1867_uploaded_files), server will core dumped on
the next form-data post request.
So It's a simple oneline-fix.
I have attached a patch for this, patch tested on Mac OS X 10.6.7 & Redhat
Linux.
thx.

Description:
------------
Post two multipart/form-data to the cli-server, one 200 request and one 404
request will cause the cli-server segfault. if enabled debug, the server exit
with
a message: "in-consist hashtable".
Test script:
---------------
1.Start the cli-server
2.Touch a simple empty php script
3.Make the requestes
$ curl --form a=b "http://localhost:8000/file.php";
$ curl --form a=b "http://localhost:8000/file-non-exist.php";
Expected result:
----------------
Server response correctly. one 200 and one 404 reponse.
Actual result:
--------------
Correctly response the first request. but segfault after the second 404 request.
