Okay, I've done some more investigating. I got valgrind to work on an
executable compiled using intel's c++ compiler (g++ compiled code kept
complaining about -froundingmath when I used valgrind, even though I used
the switch during compile as I should).

So what I found out was this: There appear to be no memory leaks, however
the allocated memory is huge. For 20000 identity transformations the
allocated memory was around 2.7 GB. Is there a reason that asking for level
3 optimization or other compiler switches might cause the memory to grow
like this?

Thanks for any help.
