If there's a try-finally where the try_op starts on a basic block with a
single JMP, and the JMP optimization causes that basic block to become
unreachable, then we update try_op.
In this case, there is no catch_op, so try_op is erroneously set to 0,
we should instead set it to `b->start`.
Closes GH-18110.
This should call zend_object_std_dtor() to clean the property table etc.
This also has a semantic influence because previously weak refs were not
notified for example.
This fixes the final issue in GH-18114 (the crash was master-only and
fixed already).
Closes GH-18114.
Closes GH-18123.
Preloading shutdown calls request shutdown which will deactivate the
virtual cwd state. However, further startup code still assumes the state
that was set by virtual_cwd_startup(). So we need to reactivate it
manually.
Creating a test was a bit difficult because the INI setting I wanted to
test this with is overridden by the test runner apparently.
To reproduce the issue, create an empty file test.php and execute this
in a ZTS build:
`php -d opcache.preload=./ext/opcache/tests/preload_class_alias_2.inc -d "error_log=" -d "allow_url_include=1" test.php`
Closes GH-18117.
in_array() calls are compiled to frameless calls. Adjust the
optimization appropriately. Luckily, frameless opcodes simplify the
optimization quite a bit.
Fixes GH-18050
Closes GH-18066
We destroy classes of dl()'ed modules in clean_module_classes(), during
shutdown. Child classes of a module use structures of the parent class (such as
inherited properties), which are destroyed earlier, so we have a use-after-free
when destroying a child class.
Here I destroy classes in reverse order, as it is done in zend_shutdown() for
persistent classes.

Fixes GH-15367
A frameless icall with 3 arguments is a special case because it uses
OP_DATA, but this was not added to the list, so the opline pointed to
the wrong address resulting in UBSAN report or crash.
Closes GH-18048.
This is a bit of a theoretical issue, but the maximum string length is
actually ZSTR_MAX_LEN instead of SIZE_MAX. The resulting check is a bit
slower but should still be relatively cheap.
Closes GH-18049.
Use connection ID instead of count to check whether we're using a
persistent connection. This allows the test to be run in parallel with
the other tests, but also protects against the possibility that some
other service connects to the mysql server.
Closes GH-18040
