`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

Since I can't reproduce it, and you don't seem to be getting it any
more I'll mark this bug report as closed. If it does reoccur you can
either then reopen this bug, or create a new one.
