Subject: [osx] core dump while building emacs-25
Date: Wed, 09 Dec 2015 20:20:44 -0800

`make -C ../lisp update-subdirs` on the emacs-25 branch has been
reliably causing a core dump the past two or three days.  Here are the
build logs: https://gist.github.com/dunn/ff087e9b533d373ab10b#file-03-make-L568

It doesn’t cause the build to fail (except for when I made some changes
to the source tree that I can’t reproduce; logs here if anyone’s
interested: https://gist.github.com/dunn/43f10877f11c97ab28f0#file-03-make-L291) so
I don’t know how serious an issue this is.  It occurs with -j1 and -j4,
with Clang and with GCC 5.3.0.

System config included in the logs, but for the sake of convenience:

CPU: quad-core 64-bit haswell
OS X: 10.11.2-x86_64
Xcode: 7.1.1
CLT: 7.2.0.0.1.1447826929
