To find out if your really hitting that bug or any bug, open up a TAC case.  That will be your best bet.

Thanks,

Do you've a core dump of this crash, if no then it is really hard to rootcause the issue.

#crash log is different from core dump. i think you've given crash log to tac and not core dump.

Management>> Techsupport>> controller crash>> "crash log"

#core dump of crash is not stored on WLC's flash, you need to setup an ext ftp server and configure the same on wlc.

Management>> Techsupport>> Core dump>> configure ftp server details. coredump is a bigger file that can't get stored on WLC's flash, it'll be stored to ext ftp server, the extension of file is .gz. if you've given this file then i hope cisco could rootcause the issue.
