I found out that this problem does only occurs if in the path of the file to read is a symbolic link
(/D or /J) inside.
Without symbolic links, I am not able to reproduce the issue.
Could you please try it with the use of symbolic link(s) in the path of the file to read?

Tried it with 7.0.14RC1 on Windows 10 and cannot reproduce it.

Ok, lets see. Perhaps someone else has better luck reproducing this of finding a better reproducer.
Thanks.

I tried it on 3 different windows machines with php 5.5, 5.6, 7.0 and 7.1. It can reproduce it on
all systems with all php versions.
Randomly the file_get_contents gets the error failes to open stream: no such file or directory...

Still no luck. I've changed your code to a bit shorter version
<?php
ini_set('display_errors', 1);
error_reporting( E_ALL );
$path = 'C:\path\to\file';
for ($i = 0; $i < 100; $i++) {
if (!file_exists($path)) {
die("Doesn't exist");
}
if (!file_get_contents($path)) {
die("No content");
}
}
echo "all clean";
and used up to 32 processes, but all i get is "all clean" outputs. You told you've
used other PHP versions, have you tried latest versions or just some? Also, does this reproduce on
another machine?
Thanks.

No, i use a absolute path like C:/file.zip.
The path in the script.is an absolute path for unix systems.
I am able fto reproduce the problem on windows systems with different php versions. You could maybe
try to increase the size of the for loop and the amount of php processes started in parallel.
