} Are you sure?  I get the same result in 4.2.6 and 4.3.4.

OK, it's not quite as recent as I thought -- it was fixed between 4.2.5
and 4.2.6:

        * 21701: Src/params.c, Test/D06subscript.ztst: negative offsets
        that indexed before the start of a scalar weren't handled properly.

RedHat EL 4.5 still ships zsh 4.2.0, though, so there are still going to
be a lot of stock systems out there (RHEL and otherwise) with versions
of zsh old enough to have this bug.

Seems not; 21701 fixes range-starting indices in a similar way to 23696
fixing range-ending indices.
