I followed the "resolved" thread 0000410 reporting the same problem.
I've tried the last dll (php_xdebug-2.1dev-5.3-vc6.dll) and the crash is still there.
The system Event Viewer report the following error (the original is in italian so I mention only the main data):
httpd.exe error, version, the module is xdebug-2.1dev-5.3-vc6.dll, version, error address 0x0001144f.

It seem to be a XDebug error.

Please provide the following (after picking the latest binary from http://

a. a short script that causes this problem when you're debugging through this
b. the remote debug log (see
c. a proper backtrace (see

a: the "script" is joomla, to be more precise the JFGoogleTranslator system plugin (see, the extension directory)

b: The remote debug log is quite long, if you want I can send to you by e-mail 42K file, no problem. Meanwhile I'll put here the last meaningful (I hope) lines

c: sorry but I'm approaching linux world and open source community so I cannot install the MSVC6 required for backtrace, also MSVC6 is not free (am I wrong?) and in that case I think is not a kind behaviour to crack it :-)

Derrick, I'm ready to collaborate to investigate the trouble, just ask what you need and if MSVC6 is free (I couldn't find the free download) I'll install the basics for the backtrace.

best regards

You don't have to install MSVC6, there is a free tool (also listed on that page) called Microsoft Debug Diagnostic Tools. Just scroll down to "Generating backtrace, without compiler, on Win32". Also, I need a *short* reproducing script. I am not going to debug Joomla for you :)

Hi Derick,

I've done my best to help.
I've put on this folder --> <--
the xdebug remote log and the crash dump obtained using BackTrace and MSVC6.
I still miss the xdebug symbols (I couldn't fine any on your website) and
a short script. The crash is strange and with short script I cannot
reproduce it, I can debug many files but in some particular situation
xdebug crash, in this case the crtash happen inside a call back subrotine recalled by joomla framework on a particular event... If you give/guide me in integrating xdebug symbols in Crash dump report I can try again reproducing the crash and send update information on it.

I don't want bother you neither ask to you to debug joomla, I need just some help. My mission is to set up a stable IDE for jooomla development and then share my experience. Thank you for your kind help.

Best regards
