0000797: XDebug terminates (or Eclipse loses it?) when viewing variables

FYI - I can still view the value of some variables by hovering them. Looking at the log, it seems that uses 'property_get -i 205 -n $url -d 0 -p 0', which works fine.

Can you please provide the script and the remote debug log? The smaller and self-contained the script, the better.

I did some testing and made a script for you. The problem seems to present itself when a class is calling a static method from a base class in another file. In the same file, there is no problem, and if the base class method is non-static, there's no problem. Additionally, the base class must have some property - static or non-static. With no properties on the base class, again, no problem.

I placed a breakpoint in test2.php:7 (echo 'blah blah blah';) for testing.

I can reproduce this with your scripts and remote_log.

I can no longer reproduce this. Not sure why though, but could you try the latest version from github?

I just did a git pull (8ea0093, 4/08) and a clean make, then replaced my xdebug module... still having the same issue. Not sure if it would make a difference, but the PPA with PHP 5.4 updated about a week ago. Don't know what changed in it. I also installed APC yesterday, so I just disabled and tested again - no change.

Same problem here. I'm accidentally updated my debian vbox to testing version with php 5.4 xdebug 2.2.0-rc1. @ryanp has described the problem correctly. Variables window shows a strange '::' entry too.
In log it looks like:
<property name="::" fullname="::" type="object" classname="LightWork\MVC\Router\Dispatcher" children="0" numchildren="0"></property>

Eclipse log says:
org.eclipse.php.internal.debug.core.xdebug.dbgp.model.DBGpTarget : Unexpected XML or parser failure

Don't know any relation might have.

rixbeck, ryanp: This "::" is correct. It refers to the static properties of the class. Can you paste the whole response though rixbeck? As it shouldn't really add this when there are no children. You might want to bring this up with the eclipse people too though!

rixbeck, you're still using RC1, I think I might have fixed it after that. In any case, the last context_get seems to segfault. So what would help me know is a backtrace or a (small) code example.

I see. Trying to compile the fresher one. Reporting back with the results. Thanks.

Now I have 2.2.0rc2-dev but problem still stays it seems. I'm attaching the test and log.
It is important if class B has no property, no error.
