Issue: https://github.com/php/php-src/issues/11878 Author: youkidearitai ### Description I'm trying phpdoc on <http://doc.php.net/tutorial/local-setup.php>, then displays memory leak. (My PHP environment is include --enable-debug) ```bash $ ~/php_master/bin/php -i | less Configure Command => './configure' '--enable-mbstring' '--enable-debug' '--prefix=/Users/tekimen/php_master' '--with-iconv=/opt/homebrew/opt/libiconv' '--enable-bcmath' '--with-zlib' ``` The following code: ```bash ~/php_master/bin/php -d 'ini_set("memory_limit", -1);' phd/render.php --docbook doc-base/.manual.xml --package PHP --format xhtml ``` Resulted in this output: ``` PHP: syntax error, unexpected '(' in Unknown on line 7 [02:40:04 - Rendering Style ] Running full build [02:40:04 - Indexing ] Skipping indexing [02:40:04 - Rendering Style ] Running full build [02:40:04 - Rendering Format ] Starting PHP-Chunked-XHTML rendering [02:40:05 - E_USER_WARNING ] /Users/tekimen/src/phpdoc/phd/phpdotnet/phd/Package/Generic/XHTML.php:635 Impossible to copy the http://www.php.net/styles/theme-base.css file.
