What kind of object is font_object in frame #2?

As with any Lisp object:

  (gdb) p font_object
  (gdb) xtype

Where -- in the frame where the variable is defined, in this case
frame #2 (as I mentioned above).  When -- when the program crashes, or
(if you succeed to somehow get to the same place in the code before it
crashes) before realize_default_face does whatever it does in line
5261 that causes the assertion violation.

And to get to that frame I have to type "frame 2" first which is what
I didn't know.

That was close to six years ago.  Are you still seeing this crash in a
more modern version of Emacs?

I don't even dare to try.  Rather let sleeping dogs lie.
