Bug #75445 [NEW]: User-defined assert function is optimized away with zend.assertions=-1

From: kelunik Operating system: Irrelevant PHP version: 7.2.0RC5 Package: Scripting Engine problem Bug Type: Bug Bug description:User-defined assert function is optimized away with zend.assertions=-1 Description: ------------ Execute the test script: - php -d zend.assertions=1 test.php - php -d zend.assertions=0 test.php - php -d zend.assertions=-1 test.php assert() doesn't respect the namespace fallback, but assumes unqualified calls are equivalent to \assert() and optimize it away / jump around it with assertions disabled. This is unfortunate, as few people use \assert() over assert() and wouldn't gain zero-cost assertions without this behavior. Test script: --------------- <?php namespace Test { function assert() { global $foo; $foo = true; } } namespace Test { assert(); var_dump(isset($foo)); } Expected result: ---------------- bool(true) Actual result: -------------- bool(false) -- Edit bug report at https://bugs.php.net/bug.php?id=75445&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75445&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75445&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75445&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75445&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75445&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75445&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75445&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75445&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75445&r=support Expected behavior: https://bugs.php.net/fix.php?id=75445&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75445&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75445&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75445&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75445&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75445&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75445&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75445&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75445&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75445&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75445&r=mysqlcfg
