When I configure PHP using:
./configure --enable-zend-test --enable-option-checking=fatal --enable-phpdbg --enable-fpm --enable-werror --enable-debug --enable-zts 'CFLAGS=-fsanitize=undefined,address -DZEND_TRACK_ARENA_ALLOC -DZEND_RC_DEBUG=1' LDFLAGS=-fsanitize=undefined,address CC=clang-16 CXX=clang++-16
and then attempt to run phpdbg, it crashes with an assertion failure:
phpdbg: Zend/zend_types.h:1343: uint32_t zend_gc_delref(zend_refcounted_h *): Assertion `(zval_gc_flags((p)->u.type_info) & ((1<<7)|(1<<8))) != (1<<7)' failed.
Thread 1 "phpdbg" received signal SIGABRT, Aborted.
