How do you mean "the same place"?  That place should no longer exist
after applying the patch.

If you mean the line marked below:

  /* Count how many glyphs to copy and copy the glyphs.  */
  for (area = LEFT_MARGIN_AREA; area < LAST_AREA; ++area)
    for (i = 0; i < from->used[area]; i++)
      to->glyphs[area][i] = from->glyphs[area][i];  <<<<<<<<<<<<<<

then please tell what is the value of 'area' and of 'i' at the point
of the crash.

Btw, did you compile with --enable-checking, i.e. were the 3 eassert
statements at the beginning of deep_copy_glyph_row compiled into the
program?
