Comment(by simonmar):
I have tried a program with a space leak, and can't reproduce it. Looking
at the code I can see how some of the calculations might overflow on a
64-bit machine, but not until a heap size of about 16Gb. I'll fix these
anyway, but from your results it looks more like a bug in the calculations
(something has gone negative) than an integer overflow.
