Why is this bug report not considered like a real bug ? It is because it's not
at
all the behavior expected : file_get_contents() randomly the content delivered
is
the the new symlink or from the old symlink content !!
Still occurs on PHP 5.4.6 (Linux Fedora 17).

New simplified testcase :
<?php
define('TEST_FILE1', '/tmp/testfile1');
define('TEST_LINK', '/tmp/testlink');
file_put_contents(TEST_FILE1, '42');
// create TEST_LINK pointing on TEST_FILE1 using a temporary filename (needed)
$tmp_link_name = TEST_LINK . uniqid(time());
symlink(TEST_FILE1, $tmp_link_name);
rename($tmp_link_name, TEST_LINK);
// reading this link/file
file_get_contents(TEST_LINK);
// remove the link (we have the same bug making this link pointing somewhere
else)
unlink(TEST_LINK);
$good_result = '';
// clearstatcache have no effect
clearstatcache();
// fetching result, must be empty (link does not exist)
$result = @file_get_contents(TEST_LINK);
// on bogus php it return TEST_FILE1 content
echo "TEST : " . (($result == $good_result) ?
'SUCCEED' : 'FAILED') . "\n";
echo "result : '" . $result . "' | ";
echo "expected : '" . $good_result . "'\n";
echo "php version : " . PHP_VERSION."\n";
echo "realpath_cache_size (if available) : " .
@ini_get('realpath_cache_size') . "\n";
// cleaning
@unlink(TEST_LINK);
unlink(TEST_FILE1);
?>

new summary (perhaps it would make this bug more interesting...)
Bug on 5.2.0 is verified with default configuration (without php.ini) and
sources provided from php.net (no patch from a portage).
