Bisect reveals: v5.15.2-310-ge1dccc0 commit e1dccc0d34a90e3511bfed596be9d78128ca7ee7 Author: Zefram <zefram@fysh.org> Date: Fri Sep 9 23:27:16 2011 +0100 remove index offsetting ($[) $[ remains as a variable. It no longer has compile-time magic. At runtime, it always reads as zero, accepts a write of zero, but dies on writing any other value. Cheers,

Now I see what you were seeing: -Duseithreads and -Uuselongdouble and -Umad is undertested. My bisect has been running vor two configs: -Duseithreads -Dmad and -Uuseithreads -Duselongdouble For both the bisect produced the same result. With this bisect run I also produced the first-ever pass on cpantesters for a threaded perl: http://www.cpantesters.org/cpan/report/18306813
