Comment (by rwbarton):

 Compilers built with `-O` match the current `mod73.stderr` order and
 compilers built with `-O0` match the order proposed in this ticket. Given
 that the order depends on the ids of `FastString`s, I guess this isn't
 necessarily cause for alarm, though I don't have a specific explanation
 for it.

 ezyang added support for custom output checkers in
 f8e12e2b396e0c475e1403ab8ac3fc4d63c1681e, so for now we can configure the
 test to allow either output.
