Segmentation fault when calling function after fmiUnload()

[AnHeuermann]

Description

When I call a function after fmiUnload I get an segmentation fault and Julia crashes.

How to reproduce

I have a FMU that I can't share that produces this error, but I can't get a FMU from the Modelica Standard Library to simulate because of #63. But I guess this should work for any FMU.

using FMI

myFMU = fmiLoad("someFMu.fmu")
fmiInstantiate!(myFMU)
success, simData = fmiSimulate(myFMU, 0.0, 1.0)
fmiUnload(myFMU)

fmiInfo(myFMU)

Of course I expect an error, but not a segmentation fault.

Hey Andreas,

I agree that an error message should be the way to go, instead af a crash. As you expected, this issue affects any FMU. I will try to find a nice solution for this. Until then, don't do such evil things and let that dead piece of memory in peace after fmiUnload 😅

I will have a look at this.
