    > #0  0x0043ff40 in set_cursor_from_row (w=0x8ee928, row=0xc558cc, 
    >     matrix=0x8eef58, delta=0, delta_bytes=0, dy=0, dvpos=0) at xdisp.c:13693

    Line 13693 of xdisp.c is this:

	while (/* not marched to end of glyph row */

    This cannot possibly crash.

It must be an optimization weirdness, because I have not updated that source
file since compiling.  I updated and recompiled specifically to reproduce
this in the latest sources.

It crashes with SEGV.

I can recompile with -O0 if that helps.
