New Comment:
I don't know of any small testcase. As indicated, this is 100% a
regression in PHP 5.1.3 or 5.1.4 compared to 5.1.2, it's possible to
make it appear/disappear by toggling the indicated PHP setting, and it
happens with a very popular PHP package, in the routine mentioned
earlier.
I can provide help tracing the issue, but I do not have a "10-20 line
reproducible case".

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc.
If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Description:
------------
In some circumstances, global variables will fail to be initialized
when auto_globals_jit is enabled (the default). This is a regression,
the problem did not exist in 5.1.2.
php.ini is default recommended one. Server is lighttpd 1.4.11 using PHP
in FastCGI mode.
Reproduce code:
---------------
Using for example, phpMyAdmin 2.8.0.3, and looking in the
libaries/Config.class.php code:
function checkPmaAbsoluteUri()
{
// Setup a default value to let the people and lazy syadmins
work anyway,
// they'll get an error if the autodetect code doesn't work
$pma_absolute_uri = $this->get('PmaAbsoluteUri');
if ( strlen($pma_absolute_uri) < 1 ) {
$url = array();
// At first we try to parse REQUEST_URI, it might contain
full URI
if ( ! empty($_SERVER['REQUEST_URI'] ) ) {
$url = parse_url($_SERVER['REQUEST_URI']);
}
// If we don't have scheme, we didn't have full URL so we
need to
// dig deeper
if ( empty( $url['scheme'] ) ) {
// Scheme
if ( ! empty( $_SERVER['HTTP_SCHEME'] ) ) {
$url['scheme'] = $_SERVER['HTTP_SCHEME'];
} else {
$url['scheme'] =
!empty($_SERVER['HTTPS']) &&
strtolower($_SERVER['HTTPS']) != 'off'
? 'https'
: 'http';
}
etc...
It's possible to enter this function with $_SERVER missing essential
things such as HTTP_HOST:
array(4) {
["PHP_SELF"]=>
string(21) "/mysqladmin/index.php"
["PHP_AUTH_USER"]=> (censored)
["PHP_AUTH_PW"]=> (censored)
["REQUEST_TIME"]=>
int(1147178223)
}
If auto_global_jit is disabled, this does not not happen, and HTTP_HOST
etc are set correctly.
