Environment variables in PHP 5.1.4

[Joseph Formoso <jformoso@xxxxxxxxxxx>]

All,

	I'm having some problems with a PHP 5.1.4 installation I did on
a Solaris 8 box when I try to use it with CGIwrap.  I've narrowed the
problem down to a couple of environment variables when, if both are set,
causes PHP (called in CGI mode by CGIwrap) to claim that no input file
is specified.

	The build of PHP 5.1.4 was done thus:

./configure  --prefix=/usr/local/php5 --with-ldap=/usr/local \
--enable-discard-path --disable-force-cgi-redirect --disable-cli \
--with-mysql=/usr/local/mysql5 --with-gd --with-jpeg-dir=/usr/local \
--with-zlib --disable-pear --with-xsl=/usr/local

	CGIwrap, essentially, su's to a specified UID, sets environment
variables (SCRIPT_FILENAME, etc.), and calls /usr/local/bin/php.  This 
works perfectly well except in instances where both PATH_TRANSLATED and
REDIRECT_URL are both set -- in those cases, PHP claims "No input file
specified."  PHP 4.3.9, which we were running until we upgraded to
5.1.4, doesn't display this behavior -- with identically-set environment
variables, PHP4 will properly find and execute the script where PHP5
won't.

	To give more of a concrete example of the way the environment
variables are set, the following is an example of a set which *does*
execute properly in PHP5.1.4:

------------------------------------------------------------------
     QUERY_STRING: ''
      SCRIPT_NAME: '/cgi-bin/cgiwrapd/testuser/index.php'
  SCRIPT_FILENAME: '/opt/apache/htdocs/testuser/cgi-bin/index.php'
     REDIRECT_URL: '<NULL>'
        PATH_INFO: ''
  PATH_TRANSLATED: '/opt/apache/htdocs'
      REMOTE_USER: '<NULL>'
      REMOTE_HOST: '<NULL>'
      REMOTE_ADDR: '111.111.1.111'
------------------------------------------------------------------

	However, setting the environment variables as follows causes a
"No input file specified" error:

------------------------------------------------------------------
     QUERY_STRING: ''
      SCRIPT_NAME: '/cgi-bin/cgiwrapd/testuser/index.php'
  SCRIPT_FILENAME: '/opt/apache/htdocs/testuser/cgi-bin/index.php'
     REDIRECT_URL: '/testuser/cgi-bin/'
        PATH_INFO: ''
  PATH_TRANSLATED: '/opt/apache/htdocs'
      REMOTE_USER: '<NULL>'
      REMOTE_HOST: '<NULL>'
      REMOTE_ADDR: '111.111.1.111'
------------------------------------------------------------------


	The output above is provided by CGIwrap run in debug mode, but
I've set the environment variables the same way at the command line and
then run the PHP CGI, with the same results.  Again, PHP4.3.9 works for
all these examples.

	I'm not sure if I've explained the problem properly nor given
enough information to help solve it.  I'm not even sure it's an
installation question -- I'm kinda hoping that there's a switch I've set
improperly during the 5.1.4 build which is causing the weirdness I'm seeing.

	Any suggestions are welcome, and of course I'll provide
clarification if such is needed.  Thanks for your time.
