Is this a normal build of Emacs, or did you build some branch of the
Git repository?  (I'm puzzled why the thread is called "emacs-gtk".)

>      gui_produce_glyphs (it=0x7fff82fc3650) at xdisp.c:29925
>      29925         struct font *font = face->font;
>      (gdb) next

At this point, please say

   (gdb) source /path/to/emacs/src/.gdbinit
   (gdb) bt

(replacing "/path/to/emacs" with the real location of the Emacs
sources on your system) and post the result.
