Summary: php5ts.dll crashes when specific extensions are
loaded
Status: Assigned
Type: Bug
Package: Reproducible crash
Operating System: Windows7 Ultimate x86
PHP Version: 5.4.0

New Comment:
I experiencing the same crash on two different Windows 7 Ultimate x64 machines.
Apache and PHP come up and run fine and occasionally I get the message in
error.log:
[mpm_winnt:notice] [pid 2200:tid 512] AH00428: Parent: child process exited
with status 255 -- Restarting.
At nearly the same time there are three entries in to the application event log
indicating the same error reported in bug:
Faulting application name: httpd.exe, version: 2.4.2.0, time stamp: 0x4f7ed6c4
Faulting module name: php5ts.dll, version: 5.4.0.0, time stamp: 0x4f4e7f05
Exception code: 0xc0000005
Fault offset: 0x0004c563
Faulting process id: 0x3870
Faulting application start time: 0x01cd1cb269ad9f3a
Faulting application path: C:\Apache24\bin\httpd.exe
Faulting module path: C:\PHP5\php5ts.dll
I have removed as many extensions as possible that still allows the system to
run properly. I had even gone as far as to remove php_mbstring and it didn't
change the results. Having removed some of the other extensions seem to reduce
it but this is not definitive. This is the list of what I had removed just for
reference:
php_gettext
php_ldap
php_pdo_mysql
php_pgsql
php_soap
php_sockets
php_tidy
php_xsl
I had verified that nothing required them although if that was the case you
would think that they wouldn't be doing anything to cause an error.
Interestingly enough as far as I can tell the pages are rendered properly and
that the only indication of any problem is the error.log (Apache) and Windows
events.
I am running PHP 5.4.0 and Apache 2.4.2 (ApacheLounge including
php5apache2_4.dll) and MySQL 5.6.5m8 on Windows 7 Ultimate x64 with SP1.
I have my own log file pertaining to processing of the pages and some functions
(MySQL requests are always captured) and I am trying to correlate the "crash"
to a particular event but so far nothing specific.
It is somewhat disconcerting and I do not know if there are any side issues
being created by this occurring. If anyone would like additional information
please let me know and I would be happy to submit it.

I have still the issue.
I feel that the number of crushes is increasing on my server.
I compared PHP5.4.0 to PHP5.4.0RC8. I found A difference in the configure
command options. Like this.
5.4.0
configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack"
"--disable-nsapi"
5.4.0RC8
configure.js "--enable-snapshot-build" "--disable-isapi" "--enable-debug-pack"
"--disable-isapi"
Does it have any effects on this issue?

REVELATION: Please see below, I seem to have solved my problem;
===========================
Ill explain what you asked for anyway.
Tried these configurations (all other extensions disabled, default php.ini).
-- 1
;extension=php_mbstring.dll
extension=php_bz2.dll
extension=php_gd2.dll
-- 2
extension=php_mbstring.dll
;extension=php_bz2.dll
extension=php_gd2.dll
-- 3
extension=php_mbstring.dll
extension=php_bz2.dll
;extension=php_gd2.dll.
These above all work fine.
----------
But this does not work in 5.4.0:
extension=php_mbstring.dll
extension=php_bz2.dll
extension=php_gd2.dll
-----------
DLL Versions--
Default ext files from
http://windows.php.net/downloads/releases/php-5.4.0-Win32-VC9-x86.zip
File versions all report: 5.4.0.0 / Mod@ 29/02/12 19:39
===========================
Note;
Using the RC8 Version I have done some more testing and it appears there is
something happening once php has parsed the file.
I have this code in a file:
<?php phpinfo(); ?>
If I stop the browser from continuing to load the page it gives me the entire
phpinfo output with the 3 modules apparently enabled.
Although event viewer still reports a crash.
Apache error log has nothing about this error, neither does php error log
(php_startup etc variables enabled ofc).
===========================
Revelation!?;
Now back with 5.4.0 Official, re-ran phpinfo.php with all 3 ext enabled and now
it shows the page properly with NO CRASH.... Strangely fixed!?
All versions now working;
Apache 2.4.1/Apache2.2.17 + PHP 5.4.0/PHP 5.3.10
----------------
Following Ext enabled on working 5.4.0 Offical:
extension=php_mbstring.dll
extension=php_bz2.dll
extension=php_gd2.dll
extension=php_curl.dll
extension=php_mysql.dll
extension=php_mysqli.dll
extension=php_sqlite3.dll
extension=php_fileinfo.dll
extension=php_gettext.dll
extension=php_intl.dll
extension=php_pdo_mysql.dll
extension=php_pdo_sqlite.dll
extension=php_sockets.dll
extension=php_tidy.dll
extension=php_xmlrpc.dll
extension=php_exif.dll
Only the 3 ext causing issues were enabled in RC8 dir.
This is extremely puzzling. Steps I took while testing:
Replace the official 5.4.0 dir with the RC8 5.4.0 dir,
Restart and test error several times trying to stop processing of phpinfo page
long enough to look.
Re-replace 5.4.0RC8 dir to Official.
Re-Test.. no Crash.. Fixed?
===========================
Testing RC8 Again..
phpinfo page loads and crashes once loaded. Everytime. (5/5).
Official Once again..
Everything works fine...
===========================
This leads me to believe RC8 has had some part in this.
Perhaps a remnant dynamic configuration with apache.
For now, I appear to have solved my problem. But I do
still believe there is some inherent instability with
these 3 extensions even in the official build.
Thanks

You said "I removed some and it works", or something along this line...
@matt, please follow that further. As in, load this 3 DLLs with the given
versions
and see if it works in the same configuration.

Are you unable to read the original bug report or something, the dll files in
question were mentioned in the description...
This should be looked into, it means you cannot use mbstring, curl and GD2 at
the same time, which is not good at all. They all serve a very useful purpose.
There is obviously some compatibility issue with these dll's.
If you cannot read the original bug report, then here;
php_mbstring.dll
php_gd2.dll
php_curl.dll
--
This is using a default setup as explained above on a system more than capable.
And trust me, I am by far no beginner in using PHP, compiling my own versions
with custom extensions etc. Trust me when i say, this should not be happening.
PHP5.3.10 has NO problems using all 3 extensions.
only PHP 5.4.0.
Thanks.
