bug#19276: 25.0.50; Crash on startup on OS X with -Q

[Kirill Ignatiev]

Emacs invoked with "-Q" (git development version) crashes on startup.
This happens sometimes, not always. I already posted a bug related to
this, but that was for version 24.4.

To reproduce: run emacs with "-Q" repeatedly until it crashes. This
might take some tries, but on my computer it eventually crashes with
the stack trace below.

(lldb) run -Q
