Out of Memory Error -- Possible Leak?by Anonymous Monk

Anonymous Monk has asked for the
wisdom of the Perl Monks concerning the following question:
G'Day Oh Wise Ones
I come to ye with some great confuzzlement. I have a loop like so:
This loop does crash. And, it is apparently the foreach that is causing the crash, as this still crashes:
But importantly this does not crash:
I should be clear: the data structures are exactly as presented. @array is a simple array, while %hash is a hash of hashes of arrays. This HoHoA is really a DBM::Deep object, however, as I had expected this to be more efficient on memory usage.
I should also point out: this code works properly with smaller datasets, but not with my full dataset, which includes millions of data-points in the HoHoA and tends of thousands in the arrays.
In my simple-minded view this indicates a memory-leak in the foreach loop. Am I missing something? In general, should I be doing something different rather than a foreach? Or am I vastly confuzzled and missing something obvious to ye great and mighty ones?
