Verified, with a trivial reporoducer
Normal user
$ echo '<?php class Foo {}' > Foo.php
$ php -d opcache.preload=Foo.php -r 'var_dump(class_exists("Foo"));'
bool(true)
Root user
# php -d opcache.preload_user=remi -d opcache.preload=Foo.php -r
'var_dump(class_exists("Foo"));'
bool(false)

I've been testing preload today on 7.4RC3 and also can't get it to work.
I don't know if its the same bug as this or unrelated, I'm testing with 2 simple scripts:
preload.php
<?php
class A{}
test.php
<?php
require_once('preload.php');
class B extends A {}
echo "ok";
when I run this without preload it works fine, when I enable preload
opcache.preload=/sambafs/preload.php
opcache.preload_user=apache
(I'm using php-fpm)
and try loading test.php I get
Fatal error: Uncaught Error: Class 'A' not found in ...
if I dump opcache stats I can see it there
[preload_statistics] => Array
(
[memory_consumption] => 3160
[classes] => Array
(
[0] => A
)
[scripts] => Array
(
[0] => /sambafs/preload.php
)
)
but its not under get_declared_classes

I confirm that this error happens as root, and also that preloading works when running as non-root,
thank you \o/

I think I find the key to reproduce this issue. You have to be root, and run with
opcache.preload_user.
e.g.
sudo ~/proj/php-src/sapi/cli/php -S localhost:8000 -t preload-failures/public/
-dopcache.preload=preload-failures/var/cache/prod/srcApp_KernelProdContainer.preload.php
-dopcache.preload_user=jhdxr
Hope this helps.

I confirm I can reproduce this issue with latest devilbox/php-fpm-7.4 docker image(588dad05d58f).
however, I got another error when I tried with my dev environment (latest 7.4 branch,
6417c507ce511ecfc5d3f3818ffb01435f3086ee).
./configure --disable-all --disable-cgi --disable-phpdbg --enable-cli --enable-debug
--enable-opcache
./sapi/cli/php -S localhost:8000 -t ~/proj/php-src-tests/bug78512/preload-failures/public/
-dopcache.preload=~/proj/php-src-tests/bug78512/preload-failures/var/cache/prod/srcApp_KernelProdContainer.php
php: /home/jhdxr/proj/php-src/Zend/zend_string.c:264: zend_string_init_interned_permanent: Assertion
`permanent' failed.
I'll try a full build later in my dev env to see if I can reproduce this issue.
