Research direction

Start by reproducing the regression introduced in V0.3.12.post1 and inspect transfer_engine_impl.cpp around line 787, where the overlapped memory region error is reported. Compare the transfer behavior with the prior version and establish what overlap should be supported; done means the reported case works without that error and is covered by a regression test.
