I waited a few days before reporting this because I'm not sure how much 
useful information I can provide in this report, but it hasn't been 
mentioned by anyone else, so here goes.

Running ./emacs in src/ within gdb (invoking it with -Q), I'm getting:

Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.

build_frame_matrix_from_leaf_window (w=0x555555b8c140,
     frame_matrix=<optimized out>) at dispnew.c:2531
2531          fill_up_frame_row_with_spaces (frame_row, 
window_matrix->matrix_x);

This is on a Linux 5.7 kernel, Debian unstable, x86-64, but I can 
replicate it on a raspi running 5.4 and stable.

It appears to be related to -nw somehow; using that triggers the crash on 
the Pi (otherwise it starts up normally).

On the first machine, configure options are "--with-x-toolkit=no 
--without-x --with-mailutils --enable-link-time-optimization".

I'm sorry I can't be more detailed, but it's kind of hard to run M-x
report-emacs-bug under the circumstances. I can, of course, test any 
patches.

You are saying that "./src/emacs -Q -nw" crashes on startup?  That
doesn't happen to me with today's master branch.

Can you build an unoptimized version, run it under GDB, and when it
crashes, show a backtrace?

Yes. It is only happening on Linux; I can build without problems on OS X.

Does building the unoptimized version require more than tweaking the 
CFLAGS entry in src/Makefile? If not, this is what I got:

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?

That being 40K of output, I have attached it to this reply.

screen(1), via ssh from iTerm2 on osx; the window is 80x26.

Thanks.  What does this produce:

  (gdb) frame 1
  (gdb) print window_matrix->rows
  (gdb) print window_matrix->nrows

What are the values of the following 3 environment variables on the
remote system: TERM, COLUMNS, LINES?

screen, 80, and 26; but te latter two are the shell builtins and not 
existing environment variables.

Thanks.  How about this:

  (gdb) frame 1
  (gdb) print frame_matrix->rows
  (gdb) print frame_matrix->nrows

OK, so this is the problem: the frame glyph matrix has no glyph rows
allocated to it.  The question is how did that happen?

To find out, please run Emacs under GDB, after setting a breakpoint in
adjust_frame_glyphs_for_frame_redisplay:

  (gdb) break adjust_frame_glyphs_for_frame_redisplay
  (gdb) run -Q -nw

When the breakpoint breaks, step through the code with the "next"
command.  The first couple of times when the function is called, it
should return immediately, here:

  if (!FRAME_LIVE_P (f))
    return;

In the call after those 2, it should allocate the glyph pools and the
2 glyph matrices, then call allocate_matrices_for_frame_redisplay, and
return here:

	  if (!FRAME_WINDOW_P (f) && pool_changed_p)
	    SET_FRAME_GARBAGED (f);
	  return;

And in the next call, it should in addition allocate the glyph rows,
here:

      else
	{
	  adjust_glyph_matrix (NULL, f->desired_matrix, 0, 0, matrix_dim);
	  adjust_glyph_matrix (NULL, f->current_matrix, 0, 0, matrix_dim);
	  SET_FRAME_GARBAGED (f);
	}

This last call's backtrace should look like this:

  (gdb) bt
  #0  adjust_frame_glyphs_for_frame_redisplay (f=0xf46948) at dispnew.c:2008
  #1  0x000000000041c905 in adjust_frame_glyphs (f=0xf46948) at dispnew.c:1828
  #2  0x000000000042cdfd in adjust_frame_size (f=0xf46948, new_width=80,
      new_height=37, inhibit=5, pretend=false, parameter=XIL(0x3690))
      at frame.c:819
  #3  0x0000000000427657 in change_frame_size_1 (f=0xf46948, new_width=80,
      new_height=37, pretend=false, delay=false, safe=true, pixelwise=false)
      at dispnew.c:5798
  #4  0x00000000004276aa in change_frame_size (f=0xf46948, new_width=80,
      new_height=37, pretend=false, delay=false, safe=true, pixelwise=false)
      at dispnew.c:5830
  #5  0x00000000004290e2 in init_display_interactive () at dispnew.c:6397
  #6  0x0000000000429561 in init_display () at dispnew.c:6449
  #7  0x00000000005a892b in main (argc=3, argv=0x7fffffffe538) at emacs.c:1995

Does this happen to you as I described, or does something different
happen?

Also, each time allocate_matrices_for_frame_redisplay is called,
please show the value of matrix_dim after the call:

  (gdb) p matrix_dim

and also show the value of f->total_lines each time
adjust_frame_glyphs_for_frame_redisplay is called:

  (gdb) p f->total_lines.

Finally, the last time adjust_frame_glyphs_for_frame_redisplay is
called, and goes on through all of its code, you should see non-NULL
value of the frame's glyph_matrix's glyph_rows before the function
returns.  Here's what I see:

  (gdb) p f->desired_matrix->rows
  $11 = (struct glyph_row *) 0xf50140
  (gdb) p f->desired_matrix->nrows
  $12 = 38

(In my case, the TTY window has height of 38 lines.)

If what happens on your system matches the above description, then
somehow the value of f->desired_matrix->rows is NULLified after this
initialization.  But if you get NULL as f->desired_matrix->rows in the
last call to adjust_frame_glyphs_for_frame_redisplay, or if Emacs
segfaults before it reaches that point, then something abnormal
happens during initialization, and we will next look at that.

Thanks.

Belatedly, yes: the problem spontaneously went away(!), after I 
accidentally full-screened my terminal emulator then restored it to 
normal size. While I am by no means certain of why that should have
such an effect, what digging I have been able to do suggests the
explanation might involve (1) a SIGWINCH that operation generated which 
(2) caused that particular screen-sessions's bash to set $COLUMNS and 
$LINES, which were previously nonextant.

I haven't been able to replicate the crash since. I can only suggest 
closing this bug report for now, and I'll reopen it if I manage to
figure out how to trigger the crash again.
