Don't bother about attaching gdb etc and Don't use emacs-devel. I suggest that you file a bug report - M-x report-emacs-bug RET - with a simple reproducible recipe. Remember to mention in the subject that it is a crash in Emacs *runtime*. If the bug is at all reproducible, someone will reproduce the bug for you and check-in a fix in no time.
