Fixed.  This is an interesting bug: It accesses "origs[-1]", and that
has been done a lot of times when running Gforth (probably would have
shown up if we used the "sanitizers" more).

It was hidden by the the result being 0 in the usual instances, and
that does not lead to an error later on.  It returned 0, because gcc
always arranged the array before to be just before origs in memory,
that was initialized to 0, and we usually don't make use of all the
elements in the array.  But an earlier long basic block in
paranoia.4th resulted in the last element of the pervious array being
set to some large value, and that led to the bug revealing itself.

A certain minimum code block size is required.  This is not handled in
a very user-friendly way, but then, --code-block-size is more of a
testing/debugging option.
