Test case same as closed #3190, while error appears to be same/similar to #3198.

Some kind of minimal regression tests for ParModelica would really be useful, to avoid bugs like this one...

For the record, I've been told this is due to the simulation runtime being compiled as C++-code, since that's what's what's used in ParModelica, while it's only valid C-code. The workaround is to not do simulations from ParModelica, or to patch the simulation runtime.

I've changed priority from blocker to high.

Fixed in 17d8596bf1869fef3c03787e99256b0c2a879ec7/OMCompiler.
Test added in a243f9eb9b3638c7b233edbe1ad27a479af3db58/OpenModelica-testsuite

Sorting these closed tickets away from "Future". Since they were closed after the last 1.9.3 release, it's very likely that they should have been part of the 1.9.4 release.
