embed sapi unable to load tokenizer, undefined symbol zend_ce_stringable

Description

Experimenting with the sample embed sapi code and build instructions from the provided readme. I also have the tokenizer extension installed. The php cli sapi works just fine. And php -m reports the tokenizer extension loaded. However, the embed sapi throws a warning about being unable to load tokenizer due to an undefined symbol, zend_ce_stringable. I suspect other extensions that utilize this class will also fail to load in the same way.

Any ideas what am I missing here? This might not be a bug (apologies if not), but I'm just not seeing what isn't being loaded to make tokenizer happy. Feels like a bug or a documentation oversight. Will poke at it some more tomorrow.

サンプルの embed SAPI コードと提供されている README/build 手順から始め、embed SAPI と CLI が tokenizer 拡張機能をどのように読み込むかを比較します。未定義シンボルの原因が embed build にあるのか拡張機能の読み込みにあるのかを確認し、警告なしで tokenizer が読み込まれるか、ドキュメントで必要なセットアップが説明されれば、issue は解決済みとします。
