ERROR 7: assertion error in symfony_demo for HYBRID+JIT1205 in both arm64 and x86

Error msg:

[07-06 02:59:11 UTC]Running : sudo php -d opcache.preload=var/cache/dev/App_KernelDevDebugContainer.preload.php public/index.php
php: php-src/Zend/zend_vm_execute.h:62757: zend_get_opcode_handler_func: Assertion `zv != ((void *)0)' failed.

This error occurred only in HYBRID mode, i.e. ZTS+HYBRID, NTS+HBRID, with JIT1205 for both arm64 and x86.

This error first occurred after this commit.

commit 2e93bb7a451a8ec6f7fcfd24a623969024907b89
Author: Dmitry Stogov <dmitry@zend.com>
Date:   Wed May 12 17:21:39 2021 +0300    Fixed possible use after free ext/opcache/zend_persist.c | 4 ++++
 1 file changed, 4 insertions(+)

Preload issue

One short call chain is zend_jit_handler -> zend_get_opcode_handler_func -> assertion
But this is not because there is some unrecognized opline in App_KernelDevDebugContainer.preload.php file.
Because php var/cache/dev/App_KernelDevDebugContainer.preload.php succeeded.

Test more JIT options under NTS+HYBRID

1202,1203,1204: pass
1205: assertion error #7

1255: assertion error #7
1252,1253,1254: pass

Note that 1255 would also result in the same error.
