Casting from pointer to array is special, so we must not fall back to
the general FFI casting. There is a particular issue regarding the
size comparison, namely that the pointer size is always 8 for 64bit
architectures, but the size of an array is determined by its
declaration, so as is casting a pointer to an array with more than 8
elements would fail, but casting to an array with less than 9 elements
succeeds, but the internal pointer would point to some arbitrary
memory.
We fix this by properly supporting the cast. An alternative would be
to deny this kind of cast generally, since it is not necessarily safe.
However, FFI isn't necessarily safe anyway.
We also check pointer/array type compatibility when casting.

By switching attribute constructor stackframe to be called via
trampoline the stack allocation is not causing dangling pointers
in the zend_observer API anymore.

If these tests fail with a fatal error, they won't properly clean up,
which likely causes other tests to fail as (several ODBC tests use the
`odbcTEST` database and tables or stored procedures named `FOO`). This
is particularly annoying during development, where you would need to
clean up manually.
We fix this by moving the cleanup code to the --CLEAN-- section, so
that this code is executed no matter what.

Unless stringified results are requested, we need to parse large
bigints as unsigned, to avoid wrap-around behavior.

When run-tests.php has been typed[1], the type of `$time` has been
chosen to be `int`. This, however, leads to truncation, and the
somewhat relevant subsecond precision is lost. We fix that by
changing the type to `float`, although `int|string` would be more
appropriate, but requires PHP ≥ 7.4.0. Another option would be to
move the `number_format()` formatting into `junit_mark_test_as()`.

This may happen, when the execute_data was allocated on the stack. We
ensure that the runtime cache pointer is not NULL before dereferencing
it.
This is a partial fix for bug 81430.
Closes GH-7665.
http2.golang.org/serverpush has been retired[1], so we need to come up
with an alternative. Until then, we mark the relevant tests as XFAIL
(although bug77535.phpt passes, what might be an indication that the
test needs further revision). To avoid waiting for the timeout, we
also unconditionally skip these tests for now.

This header declaration is never supposed to be interpreted as
definition; otherwise, the handlers are not properly initialized, what
happens, for instance, with ASan instrumented MSVC builds.
Closes GH-7827.
Like `hash_file()`, `hash_hmac_file()` expects a filename, and not some
string data. Fixing this now, constitutes a (hopefully small) BC break
though.

On NetBSD, ifconf.ifc_buf member, unlike most of platforms, is a void
pointer.
We also fix the cpuinfo declarations with empty parameter lists.

`2001:10::/28` is a reserved IPv6 range. But there's a typo in GH-7476,
which caused IPv6 address like `240b:0010::1` will be filtered by the
flag `FILTER_FLAG_NO_RES_RANGE`.

When a new process reattaches to OPcache, tracing JIT causes segfaults,
because each new process allocates its own `zend_jit_traces` and
`zend_jit_exit_groups` in SHM, although these need to be shared between
all processes.
We solve that by only allocating these structs for the first process,
and store the pointers in `accel_shared_globals`, so we can reassign
them when a new process reattaches.
Closes GH-7776.
