6047	The NF incorrectly infers the variability of a function call in Modelica.Media	Francesco Casella	Per Östlund	"Please check [https://libraries.openmodelica.org/branches/newInst/Modelica_3.2.3/files/Modelica_3.2.3_Modelica.Media.Examples.ReferenceAir.MoistAir1.err Modelica.Media.Examples.ReferenceAir.MoistAir1].

The offending code is found [https://github.com/modelica/ModelicaStandardLibrary/blob/f0e7c0d4aa6244d579e175283873ada421c89458/Modelica/Media/package.mo#L4985 here]:

Obviously, if all the inputs to the function are constant, so should be its output."	defect	new	blocker	2.0.0	New Instantiation
