Issues with Traits / php crashes

hi, i wonder if anybody out there already tried traits in more complex php applications. i am currently trying to rewrite part of a somehow complex application to use traits and i have the problem, that my scripts are dying, as soon as i include the trait. with the current php-5.4 beta my processes are dying, but with the lates snapshot, not -- i still get the message: 2011-10-16 16:41:19: (mod_fastcgi.c.2462) unexpected end-of-file (perhaps the fastcgi process died): pid: 18556 socket: unix:/tmp/php-fastcgi.socket-3 2011-10-16 16:41:19: (mod_fastcgi.c.3254) response not received, request sent: 1329 on socket: unix:/tmp/php-fastcgi.socket-3 for /index.php , closing connection ... in my logs, though. the real problem now is that i seem to be unable to isolate the issue. it seems to have something to do with properties in traits, but if i try to reconstruct this with simple example scripts, there won't be any crash. my question is: is there anything i can do to track this problem down, to get a useful backtrace / core dump or any other information, that would count as useful information for filing a bug-report? as it is know, i have nothing in my hands besides the info, that it's crashing ... thanks in advance! harald
