Emacs for Mac OS X 25.1 crashes at start under macOS 10.12.4 beta 1

[Artemio González López]

Emacs 25.1 (as well as 25.1.1rc) crashes at start under the latest developer 
beta of macOS (10.12.4 beta 1), producing the error message

2017-01-25 23:50:19.458 Emacs-x86_64-10_9[864:21038] Error -
planarGetBytes count (65536) is not a multiple of
bytesPerRow (96).

I've already reported this as a possible bug, but would like to check if 
anybody has a pointer as to what maybe the problem and how to fix it.  Any help 
would be appreciated.
