Memory leak error in ATL 8 thunk code?

Question

I am using ATL 8 and I am on a machine with DEP. The Visual Leak Detector reports a memory leak that is associated with calling HeapAlloc in atlthunk.cpp , specifically with this line of code:

 atlThunkPool = (PSLIST_HEADER)HeapAlloc(GetProcessHeap(), 0, sizeof(SLIST_HEADER)); 

And, of course, I was looking for a watch, but I could not find the corresponding HeapFree anywhere. In addition, there is a call to VirtualAlloc in the same file, i.e.

 thunkPage = (PATL_THUNK_ENTRY)VirtualAlloc(NULL, PAGE_SIZE, MEM_COMMIT, PAGE_EXECUTE_READWRITE); 

And there is no corresponding VirtualFree (except for certain conditions). Am I losing my mind or is this an ATL bug?

Thanks.
