stackoverflow not caught

When simulating the Butane models from HelmholtzMedia:
​https://libraries.openmodelica.org/branches/master/HelmholtzMedia/files/HelmholtzMedia_HelmholtzMedia.Examples.MediaTestModels.ButaneTestModel_dT.err

The 1.12 beta2 64bit on Windows crashes OMEdit, on Linux with the 1.13 nightly OMEdit does not crash, but does display the message:

[3] 17:11:57 Scripting Error
Stack overflow detected and was not caught.

Minimal test model

[Per Östlund]

I added a minimal model in case anyone wants to look into this, but this looks like precisely the kind of issue that's the reason why we're working on a new frontend. Note that the minimal model is so minimal that it's not actually a valid model anymore, but it still gives the same stack overflow.

[Martin Sjölund]

With -d=-scodeDep you get further, but it still gets a stack overflow.

[Francesco Casella]

With the NF, the flattening currently stops ​here

Error: Constant fluidConstants[1].molarMass is used without having been given a value.

This is actually the same issue reported in #4918, so I would consider the original issue of this ticket solved for 2.0.0 (i.e. assuming you will use the new front-end).
