This problem is now solved, the front end fails later during NFCeval with 

[OpenModelica/OMCompiler/Compiler/NFFrontEnd/NFCeval.mo:1900:20-1900:79:writable] Error: 
Internal error NFCeval.evalBuiltinAbs got invalid arguments
({48000.0, 44000.0, 40000.0, 24000.0})

Actually fixed by ​PR 7350.

It was actually still failing during the flattening, just in a different way. With this fix it now gets as far as compilation of the generated C-code, where it fails due to what is probably more frontend issues.
