Where to place declaration of struct SimulationData

[MatthiasFreimuth]

Is there a reason, why SimulationData is filled/ initialised early in nonlingeo_precice.c and not just right before it is used in Precice_Setup?
For a testcase of mine it happens, that the data within SimulationData seems to be alternated in between declaration and usage and therefore some values are not correct when calling Precice_Setup. I would guess that the size of some fields inside the struct differ in between, so we have a problem of memory allocation or access.
For my case it helped to move the struct SimulationData part right in front of the Precice_Setup call.

In #135 I have struggled with segmentation faults arising from memory access in trying to access initial data from SimulationData. Hence I would support moving the initialization to just before the Precice_Setup call. Have you already tried this out?
