[ale] C++ memory leak

[Christopher Fowler]

Is there something I can use for Perl.  I've got this program that
modules to do some of the heavy lifting.  Over time the memory usage can
go to almost 1GB.  In my part of the code I can't see anything that
would lead to a "leak".  In this case a leak being a variable where I'm
appending stuff and never deleting it.
