[php-src] Issue #12809: Segmentation fault in exception handler with CALL VM on AArch64

Issue: https://github.com/php/php-src/issues/12809 Author: pfustc ### Description Hi @dstogov, I just see a new segmentation fault issue in exception handlers on AArch64 with CALL VM debug build. I don't see this issue a few weeks ago, so it's probably caused by some recent patch. The following code: ```php <?php $error = 1 / 0; ?> ``` Resulted in this output: ``` Segmentation fault (core dumped) ``` But I expected this output instead: ``` PHP Fatal error: Uncaught DivisionByZeroError: Division by zero in /mnt/local/www/index.php:2 Stack trace: #0 {main} thrown in /mnt/local/www/index.php on line 2 ``` My PHP was built with php Zend/zend_vm_gen.php --with-vm-kind=CALL and bash configure --enable-debug. My php.ini ```ini opcache.enable_cli=1 opcache.jit=function opcache.jit_buffer_size=16M opcache.jit_debug=0x100 opcache.jit_hot_func=1 opcache.jit_hot_loop=1 opcache.jit_hot_return=1 opcache.jit_hot_side_exit=1 zend.assertions=1 ``` This can happen on general Linux/AArch64 so it's easy to reproduce. ### PHP Version PHP master @ https://github.com/php/php-src/commit/6bd680b824dbfec210d63c8dcd0f4b491cb16f8a ### Operating System Ubuntu 22.04
