Certain symbols were left unmarked, meaning they would not be emit into the final binary incorrectly. We now mark the synthetic symbols to ensure they are emit as they are already created under the circumstance they're needed for. This also re-enables disabled tests that were left disabled in a previous merge conflict. Lastly, this adds the shared-memory test to the test harnass as it was previously forgotten and therefore regressed.
