Support this issue!
In addition the xdebug socket connections to port 9000 remain established until PHP or IDE processes are terminated.
Sometimes by unknown conditions debugging started at my system (PHP x64 FCGI, PHPStorm, Win7 x64). But sometimes I can not start it. I see established connections between PHP and PHPStorm processes and message "Could not connect to client. :-(" in xdebug log.

Same issue here. If someone could send me(milkob at pdb file for xdebug 2.2.4 NTS for PHP 5.5, that would be great. I could try to debug this.

Thank you so much!

Should I mention 'size' is not being initialized?
I'm no longer having this bug since I compiled xdebug with a modification as adding "size=sizeof(sa);".

Atlanto, I think you're right. I've pushed a patch to github and put some new binaries at for you to test.

Miloslav, did you manage to find some time to look at the PDBs and debug this?

Derick, for some reason I'm not able to replicate this with version from , but I'm able to replicate with the one from . Strange enough version for PHP 5.4 also works for me, just the one for PHP 5.5 is causing the issue.

If you'd be that kind and provide me with the fixed one for PHP 5.5. nts, I'll give it a try.

Can you please try the latest code from github - on the xdebug_2_2 branch? You can get that with:

git clone
cd xdebug
git checkout xdebug_2_2

And then you can run:
make && make install

If you are on Windows, you can find new binaries at:

I ran into the same trouble as describe here on my Work Win7 x64 with PHP-nts 5.5.11 x64 and PHP-nts 5.4.27 x86.

Today I replaced the php_xdebug-2.2.4.dll's with the php_debug-2.2.5dev and it work's now like a charm ;)
