bug#23462: 25.0.93; Crash on OS X when suspending main frame

[Ivan Cibrario Bertolotti]

Emacs crashes when using the suspend-frame command (bound
to C-z by default) on the main frame.  It works correctly when the frame
is minimized by clicking on the GUI button.

Recipe: Start emacs -Q; type C-z; Emacs crashes with:
Fatal error 11: Segmentation faultAbort trap: 6

Partial crash dump from OS X console follows.  Please let me know if I can
be of further assistance.

Thanks in advance and best regards,
ICB
