Edit report at https://bugs.php.net/bug.php?id=77643&edit=1 ID: 77643 Updated by: nikic@php.net Reported by: mberchtold at gmail dot com Summary: PHP Warning: Can't preload class Zend\Db\Sql\Insert with unresolved constants -Status: Open +Status: Assigned Type: Bug Package: opcache Operating System: Windows 10 x64 PHP Version: master-Git-2019-02-21 (snap) -Assigned To: +Assigned To: nikic Block user comment: N Private report: N New Comment: Here is a minimal repro: <?php class Foo { protected $prop; } class Bar extends Foo { protected $prop = self::FOOBAR; const FOOBAR = 42; } The problem is that the constant is resolved against the wrong class, because we're reusing a property slot from the parent.

A lot of the following warnings are reported and the class is not preloaded: PHP Warning: Can't preload class Zend\Db\Sql\Insert with unresolved constants When I inspect the Zend\Db\Insert class, there are no undefined constants. Preloading only the file itself does not issue any warnings, only after all the dependent classes are preloaded. I could not figure out a minimal reproducible example, other than preloading some files from zend\db. Test script: --------------- --INI-- opcache.enable=1 opcache.enable_cli=1 opcache.optimization_level=-1 opcache.preload={PWD}/preload_undef_const_3.inc preload_undef_const_3.inc: <?php $basedirectory = 'C:/test/'; // dependent classes opcache_compile_file($basedirectory .
