Bug #60837 [Ctl]: Segmentation fail, if use trait

Edit report at https://bugs.php.net/bug.php?id=60837&edit=1 ID: 60837 Updated by: gron@php.net Reported by: piphon at gmail dot com Summary: Segmentation fail, if use trait Status: Critical Type: Bug Package: Reproducible crash Operating System: Ubuntu 11.10 64bit PHP Version: 5.4SVN-2012-01-22 (SVN) Block user comment: N Private report: N New Comment: Hi, I was not able to reproduce the problem, because I do not have the necessary setup. Think, I got as far as that PDO complains about a missing database table, but I also changed the db driver from mysql to sqlite. The only thing I saw was that on an old checkout, the bug with doccomments #60809 caused segfaults. But, that seems unrelated to the stacktrace below.

Yes. Finally recreated it.
