The hashref is being evaluated as a number, which returns the numeric
address of the referee.
On HP-UX, that means you're trying to access an array element with index
1,073,867,976. Presumably, HP-UX is refusing to allocate 1,073,867,977
scalars, making ary[1,073,867,976] (or thereabouts) a bad pointer. (I
don't know whether 'ary' is null or not, and I'm not really in a
position to check--I don't have a Perl with debug symbols handy.)
On OS X, you're trying to access element 2,667,044. Apparently this is
okay on your box (although I'm guessing Perl's eating a few extra
megabytes). However, note the caveat in L<perlsyn/Foreach Loops>:
If any part of LIST is an array, foreach will get very confused
if you add or remove elements within the loop body, for example
with splice. So don't do that.
That's good advice on both of these problems, really--don't do that.
