See SR-12893. swift-reflection-dump does not properly handle offsets in ELF executable images that, when interpreted as vaddrs, belong in segments part of the image. This just empirically XFAIL's the unit tests that are crashing or failing, even though the other tests are just happening to pass anyway. There's no clear workaround; disable the expected failures for the moment.
