Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
No reproduce on my side as well, checked on win10 and win7. Maybe there'll be more info if you
could supply a dump or at least a backtrace.
Thanks.

VC14 redistributable x86 is installed correctly.
PHP 7.1.8 NTS x86 is running without problems on my system, but only this one function (is_file)
with parameter (length > 260) will fail!
PHP 7.0.22 NTS x86, PHP 7.1.8 NTS x64 and PHP 7.1.8 TS x86, will work fine with the test-script.
We checked the script on my collegues pc and, there is the same error, he also has Win 7 Pro x64.
I downloaded a vm from: https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
(VM: IE10 Win7 (x86), Plattform: VMware) to test it and the php process will also die in the vm.
On the vm, i only installed visual c++ redist 2015 x86 and downloaded PHP.
Windows gave me the following infos:
<WERReportMetadata>

Have now tested with all 4 official release builds on both W7 x64 and W10 x64, cannot reproduce in
any configuration.
I don't have any x86 Windows installations handy to test against.
------------------------------------------------------------------------
[2017-08-14 09:41:27] daverandom@php.net
I cannot reproduce this on Win 10 x64, tried with php-7.1.8-nts-Win32-VC14-x64,
php-7.1.8-nts-Win32-VC14-x86, and php-7.1.8-Win32-VC14-x64.
Please can you double check that you have the x86 VC14 redistributables correctly installed on your
system?
Test script:
---------------
C:\Users\chris.wright>d:\temp\php-7.1.8-nts-Win32-VC14-x86\php.exe -c
d:\temp\php-7.1.8-nts-Win32-VC14-x86\php.ini-production -r "$data = str_pad('', 461,
'x'); var_dump(is_file($data));"
bool(false)

Description:
------------
When i check a string if it is a valid path, and the string is longer then 260 chars, the
php-process (cgi and cli) will crash.
I use a fresh downloaded php 7.1.8 (VC14 x86 Non Thread Safe (2017-Aug-02 00:22:56)), with the
default php.ini from the archive.
cmd: .\php.exe -c .\php.ini-production C:\phptest.php
Operatingsystem: Windows 7 Professional SP1 with all updates installed.
Test script:
---------------
<?php
$data = str_pad("", 261, "x");
is_file($data);
