Wrong generated code for a model of the Buildings library

[mwetter]

The following commands give a segmentation fault on Ubuntu 14.04, 64 bit:

$ export OPENMODELICALIBRARY=pwd:/usr/lib/omlibrary
$ omc +d=nogen,initialization,backenddaeinfo,discreteinfo,stateselection openmod.mos

where openmod.mos has the content:

system("rm -f Buildings_* Buildings.* Modelica_*");
loadModel(Modelica, {"3.2.1"});
getErrorString();
loadModel(Buildings); getErrorString();

simulate(Buildings.Fluid.Storage.Validation.HeatExchangerDynamics);

// division by zero (but model seems OK) simulate(Buildings.Fluid.HeatExchangers.Examples.DryEffectivenessNTUMassFlow);

system("rm -f Buildings_* Buildings.* Modelica_*");

Looking at the report in ​https://test.openmodelica.org/libraries/Buildings/files/Buildings.Fluid.Storage.Validation.HeatExchangerDynamics.err

Buildings.Fluid.Storage.Validation.HeatExchangerDynamics_06inz.c:3823:45: error: use of undeclared identifier '$PtanDyn$PQHex_flow_nominal'
  data->simulationInfo->realParameter[86] = $PtanDyn$PQHex_flow_nominal;
                                            ^

                                             ^

it seems that we still have a problem with the generated code. No segfault, though.

Rescheduled to 1.14.0 after 1.13.0 releasee

This issue has been solved in the new front end a long time ago. The model currently fails because of #5238
