I see the problem, but I don't yet understand how it happens.

What is the value of windows_or_buffers_changed?  IOW, what does this
print:

 (gdb) p windows_or_buffers_changed

Also, can you try adding this line:

  f->fonts_changed = true;

after this line in frame.c:x_set_font (should be around line 3650 in
frame.c):

  /* Attempt to hunt down bug#16028.  */
  SET_FRAME_GARBAGED (f);  <<<<<<<<<<<<<<<<<<<<<<<<<<

Please add that here, and see if the crashes go away.

Thanks.
