This happens because on ZTS we execute `executor_globals_ctor` which reset the `freelist` and `p5s` pointers, while on NTS we don't. On NTS we can reuse the caches but on ZTS we can't, the easiest fix is to call `zend_shutdown_strtod` when preloading is shut down. This regressed in phpGH-13974 and therefore only exists in PHP 8.4 and higher.
