Sorry for the delay. I recall that exactly this issue has already popped
out. I think that the current code is fine and there is nothing to fix.
However, given that it happens in already released stable GCC, it seems
like after all we have to do something about it. These are mostly
theoretical code paths, so the way it's fixed doesn't really matter
much. It would probably be more appropriate to add
assert(SUCCEEDED(hres)); after IsClassOfCategories calls, which can't fail.
