Encountered an ICE while using a polymorphic type. Not sure what the precise cause of the error was. This gist: https://gist.github.com/AyeGill/5594429
contains the error log and the code used to implement the type as well as the point at which it is used. I'm sorry I can't help pinpoint the cause of the error more precisely. This code: https://gist.github.com/AyeGill/5594548
failed to experience the same error despite featuring similar uses of polymorphism.

Do you have a complete code sample where this issue still occurs? The one in the first gist isn't compilable.

Closing due to the lack of a reproducible test case.

Fix the ICE 6539

Fixes rust-lang#6539

It happened because `zero_sized_map_values` used `layout_of` with types from type aliases, which is essentially the same as the ICE 4968.
