Fixes this valgrind warning:

 Conditional jump or move depends on uninitialised value(s)

    by  PROFILE_GetPrivateProfileString (profile.c:1110)
    by  GetPrivateProfileStringW (profile.c:1224)
    by  GetPrivateProfileStringA (profile.c:1192)
    by  test_GetPrivateProfileString (profile.c:511)
    by  func_profile (profile.c:611)
    by  run_test (test.h:488)
    by  main (test.h:537)
  Uninitialised value was created by a client request
