FMU library - fmi2FreeInstance

[mantielero]

Well, I fixed it with:
    
    
    proc fmi2FreeInstance*(comp: ModelInstanceRef) =
        `=destroy`(comp[])
        GC_fullCollect()
    
    
    Run

I hope this helps others.

Valgrind says:
    
    
    ==716751==
    ==716751== HEAP SUMMARY:
    ==716751==     in use at exit: 0 bytes in 0 blocks

    ==716751==
    ==716751== All heap blocks were freed -- no leaks are possible
    ==716751==
    ==716751== For lists of detected and suppressed errors, rerun with: -s
    ==716751== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
    
    
    Run

So this looks good.
