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.

Description:
------------
I'm trying to preload zend framework 3. 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 .
'vendor/zendframework/zend-db/src/Adapter/Platform/PlatformInterface.php');
opcache_compile_file($basedirectory .
'vendor/zendframework/zend-db/src/Sql/SqlInterface.php');
opcache_compile_file($basedirectory .
'vendor/zendframework/zend-db/src/Sql/AbstractSql.php');
opcache_compile_file($basedirectory .
'vendor/zendframework/zend-db/src/Sql/PreparableSqlInterface.php');
opcache_compile_file($basedirectory .
'vendor/zendframework/zend-db/src/Sql/AbstractPreparableSql.php');
// actual class
opcache_compile_file($basedirectory . 'vendor/zendframework/zend-db/src/Sql/Insert.php');


Expected result:
----------------
No warning

Actual result:
--------------
PHP Warning:  Can't preload class Zend\Db\Sql\Insert with unresolved constants
