See Update 1. The rate of growth shown there stays the same throughout the life cycle of the script (which is what I mean by permanent).

If you need anything else let me know!

Is that the exact code from the OP?

Because when I run that code (Vista;(v5.18.4) built for MSWin32-x64-multi-thread) with:

• Option 2: 22.4MB constant regardless of how long I run it.
• Option 4: 22.3MB.
• Option 5: 23.3MB.

Which brand (AS/Strawberry/self-built) of Perl are you using?

I'm with torvalds on this Agile (and TDD) debunked I told'em LLVM was the way to go. But did they listen!

Yes, that is the exact code run on the test system. I've also included another update indicating system information and perl -v output.

For what its worth, the systems I'm testing this on are virtual machines, and are experiencing some issues. I just did not think these issues could/would cause a problem like this?

Running the code on my workstation, on active perl 5.20.2, i too see no memory leak and similar numbers.
