2510	OpenModelica computes incorrect results if equations are slightly reformulated	Michael Wetter	Willi Braun	"For the code section below, OpenModelica computes different values for the variables wrong and hMed_out:
{{{
  XiVap = XiActual[i_x];
  wrong    = (hActual -(1-XiActual[i_x]) * hCon);
  hMed_out = (hActual -(1-XiVap)         * hCon);
}}}

This code is in https://github.com/iea-annex60/modelica-annex60/blob/issue17_enthalpySensor/Annex60/Fluid/Sensors/LatentEnthalpyFlowRate.mo#L69

The problem can be reproduced by running testOpenModelica.sh as on https://github.com/iea-annex60/modelica-annex60/tree/issue17_enthalpySensor
