Get rid of that.  You are releasing the interface too many times.  When
QueryInterface() returns, the interface has a reference count of 1, and
TComInterface is taking ownership of the interface pointer.  Then you are
calling Release() to manually decrement the count to 0, destroying the
interface object.  But TComInterface is then decrementing the reference
count again when it itself is freed, which will crash since the interface
object is no longer valid.  The whole point of using TComInterface is that
it handles the reference counting for you automatically so you don't have to
do it yourself manually.
