see, 

 % php -v

but i also am 'missing' the 

	with eAccelerator ...
	with Xdebug ...


where,

 % php -m | egrep -i "eaccelerator|xdebug"
    eAccelerator
    xdebug
    Xdebug
    eAccelerator

 % php-cgi -m | egrep -i "eaccelerator|xdebug"
    (empty)


given,

Dmitry, you can commit that patch..or if you don't have time, I can do
it. :)

I had a discussion with Dmitry a few weeks ago and got directed towards
an onexit handler for dealing with module cleanup since my issue was
aimed at MySQL on Win32.

If other people are having problems then it may be worth while patching
it, I've created a patch at
http://server.macvicar.net/patches/cgi_main.c.patch

Description:
------------
The CGI SAPI initializes extensions through the regular MINIT/RINIT
functions, but lacks a call to php_request_shutdown() for proper
extension shutdown on some command line options. This is the case for
command line options -v, -i and -m, which call exit(0) without
requesting module/extension shutdown first.

The CLI SAPI *does* clean up nicely after -v/-i/-m and does not exhibit
this behavior.

Reproduce code:
---------------
With CGI SAPI:

# php-cgi -v
PHP 5.2.4RC3 (cgi-fcgi) (built: Aug 27 2007 16:51:33)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
    with eAccelerator v0.9.6-dev, Copyright (c) 2004-2007 eAccelerator,
by eAccelerator
[23661] EACCELERATOR: PHP unclean shutdown


With CLI SAPI:

# php -v
PHP 5.2.4RC3 (cli) (built: Aug 27 2007 16:51:49)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2007 Zend Technologies
    with eAccelerator v0.9.6-dev, Copyright (c) 2004-2007 eAccelerator,
by eAccelerator


Expected result:
----------------
nice clean shutdown through RSHUTDOWN/MSHUTDOWN.

Actual result:
--------------
exit(0) without shutting down modules/extensions
