I run the Mac OS (X) binary distributions built by David Caldwell at www.emacsformacosx.com, which claim to be pure GNU Emacs. The latest pretest 25.1.90 immediately crashes on OS X 10.10.5 Yosemite.
$ emacs -nw -q
Illegal instruction: 4
I can't really give much more information. 25.1 and all of its protests and release candidates ran fine, and the released version continues to do so.

It would help if you could run Emacs under a debugger and show
backtrace when it crashes.
Thanks.

Sadly this is not as informative as it looks:

This looks like the crash is inside libnettle, a shared library used
by GnuTLS. Could it be that you have an incompatible binary of that
library?
In any case, the problem doesn't seem to be in Emacs.

It's been over ten weeks with no response, so I'm going to close this
bug. If you need further help you can still reply to this, or it might
be worth checking with the Emacs for OS X people to see if there are any
pre-requisites.
