MDDSpaceMouse.c: XOpenDisplay failed 

Internal error: the calling thread has no OpenModelica thread data, so the error cannot be handled and the simulation is aborted.
This happens when the simulation executable or an external library links its own copy of the pthread library (e.g. a static libwinpthread) instead of the one the OpenModelica runtime uses.
