This regressed in cd53ce838a.
The loop with `zend_hash_iterators_update` hangs forever because
`iter_pos` can't advance to idx. This is because the
`zend_hash_iterators_lower_pos` upper bound is `target->nNumUsed`,
but that is set to `source->nNumOfElements`.
That means that if there are holes in the array, we still loop over all
the buckets but the number of bucket slots will not match.
Fix it by changing the assignment.
Closes GH-12831.
This has been the case at least since PHP 5.4. Thanks to Girgias for
pointing it out.
It appears that there are several global variables internal to mbstring
which can be queried via mb_get_info() and which could be NULL, but
at the very least, we know that "mbstring.http_input" is one of them.
* fix segfault in `ZEND_BIND_STATIC`
In case a `ZEND_BIND_STATIC` is being executed, while the current chunk is full,
the `zend_array_dup()` call will trigger a OOM in ZendMM which will crash, as
the opline might be a dangling pointer.
* add missing test
* `assert()`ing seems easier than trying to make the compiler to not optimize
* moved from function call to INI setting, so we can use this in other places as well
* make `assert()` work no NDEBUG builds
* document magic number
* fix segfault in `ZEND_FUNC_GET_ARGS`
In case a `ZEND_FUNC_GET_ARGS` is being executed, while the current chunk is
full, the `zend_new_array()` call will trigger a OOM in ZendMM which will crash,
as the opline might be a dangling pointer.

php_strip_url_passwd modifies url in-place. We cannot assume from
php_message_handler_for_zend that data is a temporary, modifiable string.
Fixes oss-fuzz #64209

Right-shifting a negative number is unspecified (i.e.
implementation-defined) behaviour [1]. If we take a look at the
generated assembly [2], we see that the wrong value is computed.
Fix it by using Z_UL instead of Z_L.
While we're at it, just change every occurrence of this pattern to use
Z_UL instead of casting.

Fixed GH-10008: Narrowing occurred during type inference of ZEND_ADD_ARRAY_ELEMENT
ext/intl: change when the locale is invalid for the 8.1/8.2 serie.
