10d43c40dd ext/opcache/zend_shared_alloc: change "locked" check to assertion 
Calling zend_shared_alloc() without holding the lock is always a bug,
not a fatal runtime error.

e217138b40 ext/opcache/jit/zend_jit_trace: add missing lock for EXIT_INVALIDATE 
Commit 6c25413183 added the flag ZEND_JIT_EXIT_INVALIDATE which
resets the trace handlers in zend_jit_trace_exit(), but forgot to
lock the shared memory section.

This could cause another worker process who still saw the
ZEND_JIT_TRACE_JITED flag to schedule ZEND_JIT_TRACE_STOP_LINK, but
when it arrived at the ZEND_JIT_DEBUG_TRACE_STOP, the handler was
already reverted by the first worker process and thus
zend_jit_find_trace() fails.

This in turn generated a bogus jump offset in the JITed code, crashing
the PHP process.

b26b758952 ext/opcache/jit: handle zend_jit_find_trace() failures 
Commit 6c25413 added the flag ZEND_JIT_EXIT_INVALIDATE which resets
the trace handlers in zend_jit_trace_exit(), but forgot to consider
that on ZEND_JIT_TRACE_STOP_LINK, this changed handler gets passed to
zend_jit_find_trace(), causing it to fail, either by returning 0
(results in bogus data) or by aborting due to ZEND_UNREACHABLE().  In
either case, this crashes the PHP process.

I'm not quite sure how to fix this multi-threading problem properly;
my suggestion is to just fail the zend_jit_trace() call.  After all,
the whole ZEND_JIT_EXIT_INVALIDATE fix was about reloading modified
scripts, so there's probably no point in this pending zend_jit_trace()
call.

45cb3f917a Fix a memory leak in tracig JIT when the same closure is called through Closure::call() and natively. 
Closure::call() makes a temporary copy of original closure function, modifies its
scope, resets ZEND_ACC_CLOSURE flag and call it through zend_call_function().
As result the same function may be called with and without
ZEND_ACC_CLOSURE flag, that confuses JIT and may lead to memory leak or
even worse memory errors.

The patch allocates "fake" closure object and keep ZEND_ACC_CLOSURE flag
to always behave in the same way.

By default, the system allows these but admin can disable them system wide.
However the procctl api permits to control it per process.
