Yes, it is yet another latent bug which I had not yet tracked

exposing latent bugs I could not fix. All of the intervening patches have
been for latent bugs leading to this patch, but apparently there still are
more.
The following link is my reply to Richard Henderson's original
approval of the patch where I withdrew it due to failures I discovered:
