Hi there,

I compiled php-src with clang13 and gcc11. For the following script, `sapi/cli/php` emits warning message "Warning: Undefined variable $b", but

For clang13 compiled one, the warning says the error happens on line 3.
For gcc11 compiled one, the warning says the error happens on line 2.

Test script:
---------------
<?php
$a = 0;
var_dump($b::class);
?>
