Where did you get Apache from? If you got it from apache.org you need the VC6 binaries of PHP and Xdebug.

I'm having this problem aswell.

I'm using the apache 2.2.11a binaries from apachelounge.com
I'm using the same php version as above

When i start php.exe -v i see that xdebug is loaded properly. Also when i use the same method to retrieve the phpinfo() information everything works OK

But when i load php as a module in apache, everything works untill i request the first .php page and then tells me the apache program crashed and what was the faulting dll file. The faulting dll file is php_xdebug.dll according to windows.

Hope this helps

I've verified this problem with the cli version of php:

• php.exe from
  http://windows.php.net/downloads/releases/php-5.3.0-Win32-VC9-x86.zip
  (I wish they put a "-ts-" in the filename so it's easier to
  distinguish from "-nts-").

• http://xdebug.org/files/php_xdebug-2.0.5-5.3-vc9.dll

Incidentally, in the php.ini file I need to have
zend_extension point to the xdebug DLL --
"zend_extension_ts" does nothing

PHP can safely load xdebug, but at the start of a debugging
session PHP crashes.

This is on Vista.

Debugging works with both ts and nts for VC6, and nts for VC9/x86.
I haven't had a chance to test the x64 builds yet.

php_xdebug-2.0.5-5.3-vc9.dll is really version 2.1.0dev (check the attached version info)
Compiled from 2.0.5 source the dll file seems to work ok.

eis_os: where's the attached version info? And how did you get it?

You can right click the dll and see the file version, when starting php in cli mode it shows 2.1.0-dev or the brute force variant: open the dll in some editor and look for API2009, the next string is the versions number.

As noted, I compiled a vc9 thread safety version from source because I had the same crash and currently I don't seem to have a problem with my compiled version. So php_xdebug-2.0.5-5.3-vc9.dll on the server is currently version 2.1.0-dev (TS,VC9) and it will crash php5.3. Derick has to upload the right version.

Please try the php_xdebug-2.1 versions from http://files.derickrethans.nl/xdebug-2.1-all.zip — they should have a fix. Make sure you use the correct VC version with your version of apache. The apache from apache.org requires VC6, the apache from apachefriends requires VC9 builds of PHP and Xdebug.

php_xdebug-2.1dev-5.3-vc9.dll - works for me :D

hmmm after some testing there are still some problems.

the dll loads and shows properly on the phpinfo page.

Also when i create a page which forces an error xdebug properly shows the error properly and in xdebug style.

But every now and then apache crashes and shows php_xdebug.dll as the source of the crash. This happens especially often when loading the first page of phppgadmin and phpmyadmin. The error occurs with those scripts about 95% of the times i tried to load it.

Maybe this helps: szAppName : httpd.exe szAppVer : 2.2.11.0 szModName : php_xdebug.dll
szModVer : 2.1.0.0 offset : 00005ef6
