Submitted: 2009-12-14 19:31 UTC Modified: 2010-01-19 19:13 UTC
From: donraman@php.net Assigned: ksingla (profile)
Status: Closed Package: WinCache (PECL)
PHP Version: 5.2.11 OS: Windows
Private report: No CVE-ID: None
 [2009-12-14 19:31 UTC] donraman@php.net
Description:
------------
There are two distinct instance where WINCACHE crashes and makes PHP CGI to crash or go to a state where browser displays white page. Details about fault is:

????Ӧ?ó??? php-cgi.exe???汾 5.2.11.11??ʱ???? 0x4ab13019??????ģ?? php_wincache.dll???汾 1.0.1117.0??ʱ???? 0x4b05d476???쳣???? 0xc0000005??????ƫ???? 0x00008ac5?? ???? ID 0x15f8??Ӧ?ó???????ʱ?? 0x01ca7730a82ee192??

The other one is at:
????Ӧ?ó??? php-cgi.exe???汾 5.2.8.8??ʱ???? 0x493d79ac??????ģ?? php_wincache.dll???汾 1.0.1117.0??ʱ???? 0x4b05d476???쳣???? 0xc0000005??????ƫ???? 0x00012aba?? ???? ID 0x1660??Ӧ?ó???????ʱ?? 0x01ca7705cd0e93b9??

Reproduce code:
---------------
I do not have any code which can repro this defect. I believe this defect is dependent on timing of request and hence is not code dependent but rather the way WINCACHE handles parallel requests.

Expected result:
----------------
No crash

Actual result:
--------------
Crash

This bug has been fixed in SVN.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

In case this was a pecl.php.net website problem, the change will show
up on the website in short time.
 
Thank you for the report, and for helping us make PECL better.

This bug has been fixed and checked into trunk and wincache_1_0 branch.
