Research direction
Start with ext/reflection/php_reflection.c at the assertion in zim_ReflectionProperty_isWritable, then reproduce the failure using test.php and the supplied CLI command. Compare the behavior with linked pull request #21769; done means the reproduction no longer aborts at the assertion.
