MSL and PowerSystems examples are reported with errors even though they work

[rfranke]

The nightly tests report simulation errors for these two examples:

Modelica.Electrical.Spice3.Examples.Oscillator
Modelica.Electrical.Spice3.Examples.Spice3BenchmarkDifferentialPair

See https://libraries.openmodelica.org/branches/master/Modelica_trunk_cpp/Modelica_trunk_cpp.html

The examples appear to simulate though and Oscillator should not take that long. The examples do also work with MSL 3.2.3.

Edit: the two examples do also fail for Modelica_trunk.

What is wrong?

@rfranke is this a regression or was it always like that?

[rfranke]

I assume that there is something wrong with the test setup. Just discovered that these two examples are working in OMEdit and are also reported as success for daily MSL 3.2.3 tests. One of them, Modelica.Electrical.Spice3.Examples.Oscillator, is also reported as success for daily MSL 4.0.0 tests.

@sjoelund would you mind having a look?

Here is one more example that is reported as simulation error for PowerSystems_cpp even though it works :

PowerSystems.Examples.AC3ph.Generation.Islanding

Yet another example: Modelica.Electrical.Analog.Examples.AmplifierWithOpAmpDetailed verifies since yesterday, but is still reported with the same wrong results as before, see
OpenModelica/OpenModelica@5ae02bb#diff-eb8d9f8a258b1410ea4631cd9647a54ee1e62ee6ccd11f60b11d840567024328
