> There is already a test `base7` in `declare-variant-call.f90` that tests call site with an argument. Please also note that declare variant does not support dynamic condition at the moment. Something like above will generate following error: `error: Run-time USER condition in the MATCH clause is not yet implemented`

There is no test case for checking the Run-time user condition "error". Please add one.
