ClassMetadataInfo.php of doctrine calls  ReflectionProperty->getValue() which causes a segfault. The reproducing steps are long and contain proprietary 
code. Unfortunately I have not been able to come up with something simpler. I was hoping the least this bug would do is return a result when someone 
searches for this bug. I will update if I find reproduction steps. 

Here is the phpinfo: http://pastebin.com/LnDRz8KG

Expected result:
----------------
No segfault

Actual result:
--------------

Could you run the trace again without loading xdebug?

[2015-12-03 08:32 UTC] jasonpl at swiftnetworks dot com dot au

I am running into a similar problem with doctrine and the reflection package as well. Again the code base is proprietary and again the reproduce steps appear to be long (but rather reproducible! which is both annoying and good)

Description:
Running PHPUnit I will get this crash as it is trying to populate the testing database. I have traced this particular crash back to a call against

\ReflectionProperty::getDeclaringClass()

Do crashes of this type still occur in recent PHP versions (PHP 7)?
