in thread Out of Memory

5 million nulls, even if it was double byte should take up less than 10 mb of memory no? If array overhead was double that, we're still at 20 mb of memory per copy?

What is it about the workings of this second statement that causes it to consume so much memory?

I'd like to understand how that works if anyone happens to know.

    ($nulls) = $_ = /\0/g;

    Distilling it down a little more, this also causes the out of memory error.

    Should cpanminus be part of the standard Perl release?
