Description:
------------
I'm on Windows 10.0.15063 64 bit, testing PHP 7.2.0alpha2 VC15 x86 Thread Safe.

PHP.exe fails with a combination of entries in the INI file: see the following console session:

C:\Dev\PHP7.2>php -n -v
PHP 7.2.0alpha2 (cli) (built: Jun 20 2017 20:28:13) ( ZTS MSVC15 (Visual C++ 2017) x86 )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.2.0-dev, Copyright (c) 1998-2017 Zend Technologies

C:\Dev\PHP7.2>php -n -r "echo 1+1;"
2
C:\Dev\PHP7.2>php -n -d error_log=errors.log -d error_reporting=E_ALL -d log_errors=On -d track_errors=On -r "echo 1+1;"

With this last command, php.exe fails (a popup tells me that "CLI stopped working").

If I omit one of the four INI entries above (any of them), PHP.exe works.
With all the four entries above it stops working.

Reproduced, but I'm having a hard time getting a backtrace. Can you?
http://bugs.php.net/bugs-generating-backtrace-win32.php

As far as I can tell the problem is during the attempt to open (or write to?) the error_log when PHP says at startup that track_errors is deprecated.

This issue is valid even if the INI entries are defined in an INI file, not only with the "-d" option.
