Thanks.  Please reproduce the crash again, and this time say

  (gdb) bt full

and post everything that produces.

> 0x0000555555598126 in fill_up_frame_row_with_spaces (row=0x100, upto=0)
                                                       ^^^
That 'row' pointer is clearly bogus (and causes the crash).  The
question is how does this happen.  I hope the output of "bt full" will
give some ideas.

Thanks.

P.S. Is this on some terminal emulator?  If so, which one (xterm,
something else?), and what are the dimensions of the terminal window
where you invoke Emacs?
