Last line in a buffer or last line on display? Lines that are not
displayed should not be subject to any processing during redisplay.

Do you mean that in the code below
if (TEXT_PROP_MEANS_INVISIBLE (prop) == 2)
{
struct glyph_row *row = it.glyph_row;
struct glyph *glyph = row->glyphs[TEXT_AREA];
struct glyph *end = glyph + row->used[TEXT_AREA];
int x = row->x;
for (; glyph < end
&& (!BUFFERP (glyph->object)
|| glyph->charpos < charpos);
glyph++)
x += glyph->pixel_width;
top_x = x;
}
it.glyph_row points to uninitialized memory? That would be very
strange, since start_display and move_it_to, called just above this,
already worked on that glyph row. Did I miss something?
