I think this example is out of date, currently MXNet always enable inplace_update, and the macro for shared_memory is updated as NNVM_EXEC_MATCH_RANGE

@mli we should either remove outdated examples, or keep it up to date by testing it regularly

The issue still persists. Closing the issue on github does not fix the bug.
