Description:
------------
When using include/include_once, a memory leak occur.

Reproduce code:
---------------
* Compile PHP with --enable-debug flag
* Use a PHP file with includes.

test.php:

<?php
include 'test.inc';
?>

test.inc:
<?php
?>


The following patch remove the leak:

               char *path_to_open;
       unsigned char magic[2];
       static int has_gz = -1, has_bz = -1;
+       char    *local_opened_path = NULL;

       if (has_gz == -1) has_gz = has_gzip_stream_support(TSRMLS_C);
       if (has_bz == -1) has_bz = has_bzip2_stream_support(TSRMLS_C);

       /* try to read magic */
!       stream = php_stream_open_wrapper(file_name, "rb", ENFORCE_SAFE_MODE|USE_PATH|IGNORE_URL_WIN|STREAM_OPEN_FOR_INCLUDE, &local_opened_path);
!       if  (local_opened_path)
!               efree(local_opened_path);
       if (!stream) {
               BCOMPILER_DEBUG(("error opening file '%s'..\n", file_name));
               return stream;




Expected result:
----------------
No memory leak

Actual result:
--------------
when starting test.php:

/usr/freebsd-current/php-5.2.9/main/fopen_wrappers.c(668) :  Freeing 0x28C32B4C (11 bytes), script=/tmp/t.php
