[NXC] Memory Leak

If you try to run the attached
NxProfiler-Demo.rxe, you will witness a memory leak!
It rises at about:
Or
(n * (n + 1) / 2) * sizeof(ULONG) which is about
2 * n^2.

I don't know what you are trying to report here. That your code uses more and more memory as you add elements to arrays?

Yes, but I'm only adding one element (4 bytes), and the DataspaceSize rises by the amount described in the formula above. (For example, from 49 to 50 elements, it rises by a few hundred bytes instead of the expected 4.)
The third line on the display indicates the "delta" increase in DataspaceSize.
The memory should be recycled when not in use - I know it does that normally, but for some reason it's not happening in this case. Eventually, at ~86 elements, the program gives me
File Error! -1.
