According to the splice documentation in perlfunc:

   splice ARRAY or EXPR,OFFSET

   If OFFSET is past the end of the array, Perl issues a warning, and
   splices at the end of the array.

Consider:
    perl -wle'use warnings FATAL => "all"; my @arr = qw(0 .. 10); splice(@arr, 20); print "ar is @arr"'

This generates a warning on some versions/architectures and not others.
Based on the versions tested, this appears to have regressed between 5.14.3
and 5.16.0.

no warning:

5.16.0 darwin OSX 10.6.8
5.16.1 darwin OSX 10.6.8
5.16.3 darwin OSX 10.6.8
