I tried and it didn't make any difference. 

One solution for the wrong heap context is to
destroy the dataset in the dll where it comes from.
Instead of deleting a dataset in GDALClose or directly in an app, each
driver
will provide matching Close() function that deletes/releases the dataset
returned from Open()/Create().

I think AutoLoadDrivers() will have similar problem.
