changedFeature not working with 6.0 changes

[kushti]

Surprisingly, the following test is passing in LanguageSpecificationV6 , while it shouldn't .

  property("Option.getOrElse with lazy default") {
    verifyCases(
      Seq(
        Some(0L) -> Expected(Failure(new java.lang.ArithmeticException("/ by zero")), 6, CostDetails.ZeroCost, 1793,
          newVersionedResults = {
            Seq(0 -> (ExpectedResult(Success(6L), Some(1793)) -> None))
          } ),
        None -> Expected(Failure(new java.lang.ArithmeticException("/ by zero")), 6)
      ),
      changedFeature(
        { (x: Option[Long]) => val default = 1 / 0L; x.getOrElse(default) },
        { (x: Option[Long]) => if (VersionContext.current.isV6SoftForkActivated) {x.getOrElse(1 / 0L)} else {val default = 1 / 0L; x.getOrElse(default)} },
        "{ (x: Option[Long]) => x.getOrElse(1 / 0L) }",
        FuncValue(
          Array((1, SOption(SLong))),
          OptionGetOrElse(
            ValUse(1, SOption(SLong)),
            ArithOp(LongConstant(1L), LongConstant(0L), OpCode @@ (-99.toByte))
          )
        ),
        allowNewToSucceed = true,
        changedIn = VersionContext.V6SoftForkVersion
      )
    )
  }

And it seems interpreter 6.0 is not called inside ChangedFeature functions despite following settings in VersionTesting:

  /** Tests run for both version 2 & version 3 */
  protected val activatedVersions: Seq[Byte] =
    (0 to VersionContext.MaxSupportedScriptVersion).map(_.toByte).toArray[Byte]

  private[sigma] val _currActivatedVersion = new DynamicVariable[Byte](3) // v6.x by default
