Issue: https://github.com/php/php-src/issues/10496 Author: danog ### Description Most likely caused by the changes in https://github.com/php/php-src/pull/9810 The following code: ```php <?php use danog\MadelineProto\EventHandler; use danog\MadelineProto\Logger; use danog\MadelineProto\Settings; include 'vendor/autoload.php'; class SecretHandler extends EventHandler { } $settings = new Settings; $settings->getLogger()->setLevel(Logger::ULTRA_VERBOSE); $settings->getAppInfo()->setApiId(6)->setApiHash('eb06d4abfb49dc3eeb1aeb98ae0f581e'); SecretHandler::startAndLoop('secret.madeline', $settings); ``` With this composer.json: ``` { "require": {"danog/madelineproto": "v8.x-dev#aecad0165d4c1be7e4460689c26bbfed2b5e159f"}, "minimum-stability": "dev" } ``` Resulted in a segfault, gdb backtrace: ``` #0 0x00005555558e58df in zend_unfinished_execution_gc (execute_data=0x7ffff4d7e1f0, call=0xd00000000, gc_buffer=0x5555568042e8 <executor_globals+1640>) at /usr/src/debug/php/php-8.2.2/Zend/zend_execute.c:4419 #1 0x0000555555969890 in zend_fiber_object_gc (object=<optimized out>, table=0x7fffe6bfdcd8, num=0x7fffe6bfdcd4) at /usr/src/debug/php/php-8.2.2/Zend/zend_fibers.c:672 #2 0x000055555594b168 in gc_mark_grey (stack=0x7fffe6bfdce0, ref=<optimized out>) at /usr/src/debug/php/php-8.2.2/Zend/zend_gc.c:832 #3 gc_mark_roots (stack=0x7fffe6bfdce0) at /usr/src/debug/php/php-8.2.2/Zend/zend_gc.c:986 #4 zend_gc_collect_cycles () at /usr/src/debug/php/php-8.2.2/Zend/zend_gc.c:1497 #5 0x00005555558dc1bc in zif_gc_collect_cycles (execute_data=<optimized out>, return_value=0x7fffe6bfed50) at /usr/src/debug/php/php-8.2.2/Zend/zend_builtin_functions.c:93 #6 0x00005555558eac20 in ZEND_DO_ICALL_SPEC_RETVAL_UNUSED_HANDLER (execute_data=0x7fffe6468130) at /usr/src/debug/php/php-8.2.2/Zend/zend_vm_execute.h:1250 #7 0x0000555555937248 in execute_ex (ex=<optimized out>) at /usr/src/debug/php/php-8.2.2/Zend/zend_vm_execute.h:55811 #8 0x00005555558b36de in zend_call_function (fci=<optimized out>, fci_cache=<optimized out>) at /usr/src/debug/php/php-8.2.2/Zend/zend_execute_API.c:930 #9 0x000055555596960f in zend_fiber_execute (transfer=0x7fffe6bfefb0) at /usr/src/debug/php/php-8.2.2/Zend/zend_fibers.c:504 #10 0x0000555555969392 in zend_fiber_trampoline (data=...) at /usr/src/debug/php/php-8.2.2/Zend/zend_fibers.c:299 #11 0x0000555555a03b17 in make_fcontext () at make_x86_64_sysv_elf_gas.S:78 #12 0x0000000000000000 in ??
