Constant initialization fails with inheritance

[Victorious3]

type
  A[T] = object {.inheritable.}

  B = object of A[int]

const c = B() # Error: invalid type for const: B
let d {.compileTime.} = B() # Error: cannot create null element for: [T]
let e = B() # Compiles as expected

T is qualified by B as int. I don't see why I shouldn't be able to create a compile time constant.

The first error is not related to generics, just to const with descendent objects.
