Segmentation fault in BRSL DirectionalValves models

[Niklas Worschech]

In some models of our BRSL models ocuring segmantion faults.
e.g. for the model Rexroth_Generic_Test.Hydraulics.DirectionalValves.DirectionalValve32_Easy_TC01
the gdb back trace is:

Thread 1 received signal SIGSEGV, Segmentation fault.

@niklwors reports that his colleagues found this problem is solved on 1.18.0-dev. We may try to figure out what fixed that if we really need 1.17.1 as a backup option, in case something goes wrong with 1.18.0.

@niklwors, @adrpo, please double-check and reopen, in case it's not fixed yet on master.
