Unless being able to reproduce the test failure, I can only guess that php_escape_html_entities() with ENT_HTML_SUBSTITUTE_ERRORS[1] fails. This needs further investigation.

Since this test passes on the NTS builds, I checked what the file was encoded for that and it is ISO-8859. So I believe the file being encoded as ISO-8859 is correct. The output after adding 'var_dump($out)' for TS builds: int(0) NULL ==DONE== Compared to NTS builds: int(1) string(450) "PHP Warning: PHP Startup: Unable to load dynamic library 'php_kartoffelbrei.dll' (tried: a/�/w\php_kartoffelbrei.dll (The specified module could not be found.), a/�/w\php_php_kartoffelbrei.dll.dll (The specified module could not be found.)) in Unknown on line 0 PHP 7.3.6 (cli) (built: May 29 2019 12:12:14) ( NTS MSVC15 (Visual C++ 2017) x64 ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.3.6, Copyright (c) 1998-2018 Zend Technologies " ==DONE== ------------------------------------------------------------------------ [2019-06-05 23:21:31] cmb@php.net Thanks for reporting! I cannot reproduce this test failure,though. Looking at the posted test script, there might be an issue regarding the character encoding, since the extension_dir is a/é/w (UTF-8), but the comment above states that the file is required to be encoded in iso-8859-1. Can you please double-check, that the file's encoding is what it is supposed to be? Furthermore, for debugging purposes, it might be helpful to insert a var_dump($out); after $out = shell_exec($cmd); to be able to see in bug71273.out what was actually reported by PHP. ------------------------------------------------------------------------ [2019-06-05 20:18:17] v-altruo at microsoft dot com Description: ------------ Test fails for TS build only regardless of opcache on/off.
