Nim “free(): invalid pointer” segfault (dynlib)

[Nlits]

Would you explain why? They are already defined like this:
    
    
    EventHandleProc = proc () {.gcsafe, nimcall.}
      CardSetLoadProc = proc (): Table[string, CardObject] {.gcsafe, nimcall.}
    
    
    Run

And did you mean `EventHandleProc`? `CardSetLoadProc` works without any issues.
