Sorry, that's all too obvious.  What I meant was to remove the entire

  if (window_resize_pixelwise)
    {
      width = height = 1;
      goto virtual_glyph;
    }
  else

stuff, that is from the "if" up to and including the following "else".

Anyway, I'm just about to be able to reproduce the bug here.  All I had
to do was to change the default font to some unusual value.
