When we try to load an extension multiple times, we still overwrite the
type, module number, and handle. If the module number is used to
indicate module boundaries (e.g. in reflection and in dom, see e.g.
dom_objects_set_class_ex), then all sorts of error can happen.
In the case of ext/dom, OP's error happens because the following
happens:
- The property handler is set up incorrectly in
dom_objects_set_class_ex() because the wrong module number is
specified. The class highest in the hierarchy is DOMNode, so the
property handler is incorrectly set to that of DOMNode instead of
DOMDocument.
- The documentElement property doesn't exist on DOMNode, it only exists
on DOMDocument, so it tries to read using zend_std_read_property().
As there is no user property called documentElement, that read
operation returns an undef value.
However, the type is still checked, resulting in the strange exception.

The code in the attached test used to work correctly in PHP 8.0, but not
in 8.1+. This is because PHP 8.1+ uses a more modern version of pcre2
than PHP 8.0, and that pcre2 versions has a regression.
While upgrading pcre2lib seems to be only done for the master branch, it
is possible to backport upstream fixes to stable branches. This has been
already done in the past in for JIT regressions [1], so it is not
unprecedented.
We backport the upstream pcre2 fix [2].

When declaring the same static property with a doc block in a class and in a trait,
the doc block of the property in the class is leaked. While at it, possibly fix doc
comment for internal classes.

* PHP-8.1:
Fix GH-12223: Entity reference produces infinite loop in var_dump/print_r
Fix GH-12192: SimpleXML infinite loop when getName() is called within foreach
Fix GH-12186: segfault copying/cloning a finalized HashContext
This happens because getName() resets the iterator to the start because
it overwrites the iterator data.
We add a version of get_first_node that does not overwrite the iterator
data.
Closes GH-12193.
For some reason, FILTER_CALLBACK disables the FILTER_REQUIRE_SCALAR flag that is
normally set by default. While surprising, this is not something we can change.
However, even specifying FILTER_REQUIRE_SCALAR explicitly does not corrently set
this flag. This is because FILTER_CALLBACK zeroes the flags after they have been
populated from the parameters.
We reverse the checks to make explicitly specifying the flag behave as expected.

Keep this up to date in all non-security-only branches, because the node.js
runtime for older versions might get deprecated in the future and fixing this
for all branches at once is easier.
These tests intermittently crash asan. It might be due to some function invoking
dl(), which is known to crash lsan. It might also be something else, the version
of asan shipped with ubuntu 22.04 is flaky.
In this test file, the free_obj handler is called with a refcount of 2,
caused by the fact we do a GC_ADDREF() to increase its refcount while
its refcount is still 1 because the Foo object hasn't been destroyed yet
(due to the cycle caused by the sqlite function callback).
Solve this by introducing a get_gc handler.
Closes GH-11881.
`ext/odbc/tests/config.inc` overrides the INIs used for the ODBC driver
manager pointlessly. It's not pointing to some custom PHP test suite
specific one, but the system one in `/etc/odbc(inst).ini`. Which
doesn't necessarily exist, on i.e. NixOS, MacPorts, etc.

Like oci8, procedural ODBC uses an apply function on the hash list to
enumerate persistent connections and close the specific one. However,
this function take zvals, not resources. However, it was getting casted
as such, causing it to interpret the pointer incorrectly. This could
have caused other issues, but mostly manifested as failing to close the
connection even fi it matched.
The function now takes a zval and gets the resource from that. In
addition, it also removes the cast of the function pointer and moves
casting to the function body, to avoid possible confusion like this in
refactors again. It also cleans up style and uses constants in the
function body.
