The scanner copied every doc comment into CG(doc_comment) even in non-parser mode (token_get_all/PhpToken::tokenize/highlighting), where nothing consumes it and it is immediately discarded; only do it when compiling. Also presize the tokenizer result array (one token per ~5 source bytes) and the dedup hash instead of growing them by doubling.
