I started emacs with `emacs -Q', entered the following in *scratch*,
and evaluated with C-M-x.

  (progn
    (create-fontset-from-fontset-spec
     "-*-Liberation Mono-normal-normal-normal-*-*-*-*-*-m-0-fontset-liberation")
    (set-fontset-font "fontset-liberation" 'unicode-bmp "Freemono")
    (set-face-font 'default "fontset-liberation")
    (font-at 0 nil "ɏ")       ; 0x024F: LATIN SMALL LETTER Y WITH STROKE
    (set-fontset-font "fontset-auto1" 'unicode-bmp "Freemono")
    (font-at 0 nil "ɐ"))      ; 0x0250: LATIN SMALL LETTER TURNED A

This caused a core dump:

  Fatal error 11: Segmentation fault
