Summary0000954: Crash when accessing object property in another call stack level
DescriptionI have started PHP's built-in web server. I placed a break point at some code in Netbeans. The debugger has stopped there.
Now when I choose another call stack level (see attached screenshot) and try to view `$this` -> `$config`, xdebug crashes suddenly.
Steps To ReproduceVery Complicated
Additional InformationUsed WinDbg to debug and I got this output:

I don't know when it occured the last time, so maybe it's already fixed ;-)

Okay - thanks for letting me know. I'll close it then. Please reopen if you run into this (same) problem again.
