The shortest working example:


run testcase

Use Apache 2.2.21, PHP 5.*, Win 7 x86/x64


[2012-01-11 09:12:08] bugzilla33 at gmail dot com

Description:

1. use Test script to generate crash.php, size 8192 bytes
2. now let crash php engine crash.php
3. Any php file of size 8192 bytes crashes Apache and PHP!
4. Tested with Apache 2.2.21 V9 apache longue, PHP 5.4.0 RC5 or RC6 dev on 
three other machines, Win 7 x86 or Win 7 x64.

Test script:
---
testcase php file generator:

';

 file_put_contents('crash.php',$out);

 print('1. testcase file generated: crash.php, size '.strlen($out).' 
bytes');
 print('2. now let crash php engine crash.php');
 print('3. Any php file of size 8192 bytes crashes Apache 
and PHP!');
 print('4. Tested with Apache 2.2.21 V9 apache longue, PHP 5.4.0 RC5 or RC6 dev 
on three other machines, Win 7 x86 or Win 7 x64.');
?>

Expected result:

NO crash

Actual result:
--
CRASH

Not fixed. Only a temp hack.

[PHP-BUG] Bug #54407 [NEW]: Incorrectly defined NTDDI_VERSION macro

2011-03-28 Thread pvasilevich at parallels dot com 
From: 
Operating system: Windows Server 2008
PHP version:  5.3.6
Package:  Compile Failure
Bug Type: Bug
Bug description:Incorrectly defined NTDDI_VERSION macro 

Description:

win32\build\config.w32.h.in  file contains the following code:



/* Define the minimum supported version */

#undef _WIN32_WINNT

#undef NTDDI_VERSION

#define _WIN32_WINNT 0x500

#define NTDDI_VERSION  _WIN32_WIN2K



Now look at some Windows Platform SDK file, for example ShlObj.h:



#if (NTDDI_VERSION >= NTDDI_WIN2K)



you see that NTDDI_VERSION is compared to NTDDI_WIN2K, but NTDDI_WIN2K is
defined in the following way:



#define NTDDI_WIN2K  0x0500



So, macro NTDDI_VERSION defined in php config.w32.h equals to 0x500

, but compared to 0x0500.



This is incorrect behavior and should be fixed.

Test script:
---
Schematic script:



#defined _WIN32_WINNT 0x500



#include "zend.h"

#include "ShlObj.h"



...

TCHAR ret[MAX_PATH + 1];

SHGetFolderPath(NULL, CSIDL_FLAG_CREATE, NULL, SHGFP_TYPE_CURRENT, ret);

Expected result:

NTDDI_VERSION is defined like:

#define NTDDI_WIN2K  0x0500



OR



do not unset _WIN32_WINNT and NTDDI_VERSION if they are defined.
