bug#31233: 26.1; Emacs terminated unexpectedly

[N. Jackson]

Today my Emacs crashed. This is the first Emacs crash I have seen in
many many months (years probably). This executable was built from the
emacs-26 git repo on Tuesday (2018-04-17). The instance that crashed had
been running for less than a day. I had had no previous problems with
this executable.

At the time of the crash I wasn't working in Emacs. I was working in
Firefox and other programs for more than an hour, and when I tried
to switch back to Emacs all my Emacs frames were gone.

The following backtrace was printed in my terminal emulator. I thought
that I had my system configured to write core files but I cannot find
one. My Emacs is built with debugging symbols but this backtrace doesn't
reflect that -- is there a way to convert these addresses into symbols?

  Backtrace:

  [1]+  Bus error               (core dumped) src/emacs

I am now running a new instance of Emacs under GDB so if the problem
recurs I will be in a better position to provide useful information.

Thanks.
