Summary0000830: Crash when evaluating variables from remote Eclipse IDE
DescriptionI experience an XDebug crash when trying to debug variables (either by hovering it or opening the variables pane).

First, Eclipse throws this error message:

"Unexpected termination of script, debugging ended."

The Apache error_log contains this:

"[error] child died with signal 11"

Steps To Reproduce1. Define breakpoint in Eclipse
2. Start debug session in Eclipse
3. When at breakpoint, either open variables pane or hover a variable in the editor
Additional InformationI tried using watch expressions. I noticed that if I put the name of variables I expect are strings, it works fine. But if I add an expression to evaluate an object , xdebug crashes with the error specified in the description.
TagsNo tags attached.

 Hi,

In order to reproduce and fix this, I'd need the following information:

- A *short* and *self-contained* script that reproduces the issue while debugging
- A debugging log, which you can make with setting xdebug.remote_log=/tmp/xdebug.log


cheers,
Derick

 I can't reproduce the problem outside of my Symfony 2 environment. Maybe it has to do with the autoloading mechanism?

I attach my xdebug.log file.

 It's probably not autoloading, but something to do with (static) properties instead. Could you perhaps try making a backtrace for me? (See: https://bugs.php.net/bugs-generating-backtrace.php [^])

 I uploaded the backtrace. Let me know if you need anything

 Awesome, sorry to be a pain, but could you please also run:

p *struc
bt full

 Here you are!

 Don't use -bt.2.log, I forgot to run "bt full". Use -bt.3.log instead.

 Hi, I've tried this with just Monolog, which is where the crash seems to happen. However, I have not made any success. It it possible for you to create a full setup for me, in for example a VM that I could debug?
(0002163)
nlaplante (reporter)
2012-05-17 01:00

 Yes. I opened up my app at http://nlaplante.dyndns.org:8080/app_dev.php [^]

XDebug is enabled, you can go and try it. Let me know when you're finished,

 Hi, Just having access to the website is not going to help me; I'd need shell access to probe the innards of Xdebug as well!

cheers,
Derick

 I think it would be a better idea for you to checkout a copy of my project instead. Here's the svn url:

http://svn.nlaplante.com/profolio/branches/xdebug [^]

Email me for credentials at the address in the previous comment. Thanks!

 I think I've just pushed a fix to github for this issue. Could you please try it?

 I just tested your fix and it seems to work fine. XDebug doesn't crash on variable inspection anymore, and I can dig into objects normally!
