It crashes for me systematically also with a 32-bit Emacs 25
build, such as this one (the most recent one I have):

In GNU Emacs 25.0.94.2 (x86_64-w64-mingw32)
 of 2016-05-25 built on KAEL
Windowing system distributor 'Microsoft Corp.', version 6.1.7601
Configured using:
 'configure --prefix=/tmp/emacs --without-imagemagick 'CFLAGS=-O2
 -fomit-frame-pointer -g0''
