I'm sorry I didn't recognize your problem sooner.  I've run into the
same thing, and someone from Borland determined the following
workaround.  Every exported provider X generates a function get_X, which
in its body has the line:

  *Value = IProv;

which needs to be changed to:

  *Value = (IProvider *)IProv;

Also, make sure in any existing project to change IProvider** to
IProviderPtr*.  I share your frustration that both these bugs were
introduced.
