Struct array field of pointers to struct sneaks past the recursive struct detector

[keynmol]

struct tensor {
 struct tensor * opt[5]; 
};

Generates a struct that won't compile:

  opaque type tensor = CStruct1[CArray[Ptr[tensor], Nat._5]]
  object tensor:
    given _tag: Tag[tensor] = Tag.materializeCStruct1Tag[CArray[Ptr[tensor], Nat._5]]
    def apply()(using Zone): Ptr[tensor] = scala.scalanative.unsafe.alloc[tensor](1)
    def apply(opt : CArray[Ptr[tensor], Nat._5])(using Zone): Ptr[tensor] =
      val ____ptr = apply()
      (!____ptr).opt = opt
      ____ptr
    extension (struct: tensor)
      def opt : CArray[Ptr[tensor], Nat._5] = struct._1
      def opt_=(value: CArray[Ptr[tensor], Nat._5]): Unit = !struct.at1 = value
