Suspecting heap problems, I did repeated malloc/free's before each
execution of the code to see how big my heap was.
Before the first execution, I was able to malloc up to 4.4 Mb.
After the first 8007000e error from Run, on the second execution
I was only able to malloc 3.1 Mb. The third time it was 2.1 Mb,
and the fourth time was 1 Mb (and RenderFile failed this time).
So something is eating up the heap space, even though I do all
the cleanup every time:
pControl->Release();
pEvent->Release();
pGraph->Release();
pControl = NULL;
pEvent = NULL;
pGraph = NULL;
CoUninitialize();
