It was "just" a memory leak, so it's somewhat difficult to do that. It really
takes an external tool to detect. As Rob said, it was mainly a result of
not grokking his code fully enough. There was a special macro for freeing
doubles that I didn't take into account.
Basically, for linux and FreeBSD, I took out the custom code that Rob was
using for doing allocations, and let the operating system handle it. BSD
and linux can be fussier sometimes about reading memory outside of what
you've allocated, which was sometimes necessary inside of Rob's memory
allocation code. Some preliminary tests on windows show that just using
the OS is slightly faster in some cases.
