Summary: Phpstan does not finish on Windows when opcache is

New Comment:
Further findings: this is not particularly related to Windows;
you get the same failure on Ubuntu as well, with SHM cache[1]
and with file_cache_only[2]. However, the script runs fine as
soon as Xdebug is loaded, even on Windows[3].
Interestingly, running with file_cache_only and Xdebug (3.0.4)
loaded, there are no repro/ui/vendor/atk4/core files are generated
in the file cache. That explains why the script is running fine
with Xdebug, although I have no idea why the files are not cached.
That might be an Xdebug issue.

Where else the bug should be? See the generated xdebug trace logs - I generated them in absolutely
same enviromenment without any random/time functions used inside. One with opcache enabled, one with
opcached disabled. And they differs.

On Windows with OPcache enabled, by the time
Atk4\Core\ReadableCaptionTrait is to be autoloaded,
PHPStan\Reflection\BetterReflection\SourceLocator\FileReadTrapStreamWrapper
is registered as file wrapper, so an empty file is compiled, and
the trait is not found. That happens just for that single file;
all the rest is good. I'm not sure that there is actually a bug
in php-src.

@cmb Did you get anywhere?

I'm able reliably reproduce the issue (with SHM or file cache),
and it is definitely a Windows only thing (on Linux, there are no
problems even with file cache only[1]). Debugging this on Windows
is a bit hard, due to missing helpers (like .gdbinit), but I hope
to make some real progress tomorrow.

@cmb I collected more than 100 GBs of xdebug trace logs and isolated the issue. The logs started to
be different (after I removed randomness from time() and simillar func calls) on line 210 362 792.
Here are relevant short logs:
https://github.com/mvorisek/phpstan-src/commit/f9e1b786f6a210fd8573fd8d5caf1b9cd4815e45
They differ on line 121, with opcache disabled "include" calls spl_autoload_call, with
opcache disabled, "include" returns true.
