Emacs 25.2 here doesn't crash when displaying that file, but my build
doesn't use libotf and libm17n-flt.

Can you try installing the latest versions of those libraries,
including from their development repositories?  It could well be the
problem with those libraries.  Also, if you could try the latest
development snapshot of Emacs 26.

CC'ing Handa-san who could tell more about this.
