[racket] ffi, unioun, string: is this correct?

 (define _giarg (_union _bool _int8 _uint8 _int16 _uint16
                       _int32 _uint32 _int64 _uint64
                       _float _double _long _ulong _pointer _string))

(define giarg (malloc _giarg)) (ptr-set! giarg _string "Test string")

---

It works. But I'm afraid, that string maybe allocated temporary and will be GC'ed at any time. Or _union keep _string pointer inside?
