error: aborting due to 2 previous errors; 1 warning emitted

Some errors have detailed explanations: E0601, E0732.
For more information about an error, try `rustc --explain E0601`.

[RalfJung]

The problem is that the discriminant should be ignored because of

error[E0732]: #[repr(inttype)] must be specified for enums with explicit discriminants and non-unit variants

but apparently we actually still honor it and keep going for some time with that.

We should probably set the discriminant to an error value in that case.
