This a very serious bug that stops deploying software to production. Can anyone
tell me why the status has been changed to Feedback?

Thank you for the response. I've compiled the snapshot (201206190730) and I got
segfault with same BT, only this time it occured earlier in the script.
Maybe it is worth mentioning, that I was not able to reproduce the crash with
small scripts (including only few files). The bug occurs when I use traits with
large frameworks: PHPUnit or Zend Framework.
