[vitalij]

The problem is "removeUnusedFunctions".
I guess the handling of function tree is wrong.. no merge?

same issue for:

openmodelica/cruntime/optimization/benchmark/runExReduceDrumBoiler.mos
openmodelica/cruntime/optimization/benchmark/runReduceDrumBoiler.mos

Note: after disable "removeUnusedFunctions" runReduceDrumBoiler.mos work.

[lochel]

Yes, that is true. I am already working on that issue.

[lochel]

I fixed the function tree for the three tests mentioned above. Hopefully code generation will not slow down.

Fixed in ef0a90639dc4b61612b0dc0b35fc8038ee883fb2/OMCompiler.
Tests reactivated in 4175aafeb5a7064f0e840260a49dd04e91ffc3dd/OpenModelica-testsuite
