TestState fails with assertion error on state.phase

[bilderbuchi]

With ExternalMedia 3.3.0 and OM nightly (i.e. >1.17), running ExternalMedia.Test.TestMedium.TestState fails with

The following assertion has been violated at time 0.002000
state.phase >= 0 and state.phase <= 2
Variable violating min/max constraint: 0 <= state.phase <= 2, has value: 1

Note that the printed value actually complies with the required assertion range! Maybe the passed value is a string or somesuch type that fails the assertion but looks identical when printed?

I suspect that this compilation warning (also reported in #10) could be connected:

TestState_functions.c:52:65: warning: incompatible pointer types passing 'ExternalMedia_Test_TestMedium_TestState_Medium_ThermodynamicState *' to parameter of type 'ExternalThermodynamicState *' (aka 'struct ExternalThermodynamicState *') [-Wincompatible-pointer-types]

An equivalent problem occurs in function TwoPhaseMedium_setState_pT_C_impl (see also #10).

Btw, I don't know if runtests.mos is actually used, but it's missing the tests TestMedium.TestConstants, TestMedium.TestState, TestMedium.TestSat.

A quick re-check with OM 1.18.1 and the new ExternalMedia 3.3.1 shows that this still occurs.

Probably related to OpenModelica/OpenModelica#8591.

I checked with a recent OM nightly (1.21.0-dev-318) and current master (db55653) with binaries from the CI job, and the assertion does not print anymore.

The compilation warning still occurs:

TestState_functions.c:50:70: warning: incompatible pointer types passing 'ExternalMedia_Test_TestMedium_TestState_Medium_ThermodynamicState_external *' to parameter of type 'ExternalThermodynamicState *' (aka 'struct ExternalThermodynamicState *') [-Wincompatible-pointer-types]

                                                                     ^~~~~~~~~~~

    void TwoPhaseMedium_setState_ph_C_impl_wrap(double p, double h, int phase, ExternalThermodynamicState *state, const char *mediumName, const char *libraryName, const char *substanceName)

The runtests.mos files seems heavily outdated/old, but that's probably easy to fix/not that relevant anymore.

This should be fixed with ExternalMedia 3.3.2, if used with OMC 1.21.0 or later
