SystemML 0.15
> DataType Change Test Failure
> ----------------------------
>
> Key: SYSTEMML-1575
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1575
> Project: SystemML
> Issue Type: Bug
> Reporter: Mike Dusenberry
> Assignee: Mike Dusenberry
> Fix For: SystemML 0.15
>
>
> While working on SYSTEMML-1554, an additional bug was uncovered.
> Specifically, with the IPA scalar replacement enhancement, the
> {{org.apache.sysml.test.integration.functions.misc.DataTypeChangeTest#testDataTypeChangeValidate4c}}
> test has started to fail. Looking into it, it fails due to trying to cast a
> Matrix to a Scalar object. At a deeper level, it looks like the propagated
> variable map is holding onto the "matrix" `X`, rather than dropping it as it
> should, since X is turned into a scalar by the call `X = foo(X)`.
> Interestingly, the FunctionOp for the `foo` function is marked as having an
> `Unknown` datatype and valuetype. Overall, this seems like a bug that was
> just hidden before, rather than being newly introduced.
