  * src/vm/estack.c
    * always set NIL in item allocated by hb_stackAllocItem() when it's
      used as function. In internal macro this step is missing so allocated
      item still may contain other simple value. All places in HVM where
      hb_stackAllocItem() is used are safe for such situation (I've just
      verified them again).
      It fixes problem reported by Mindaugas when hb_stackAllocItem()
      was used inside DBFFPT as temporary item and could unintentionally
      change memo type if allocated item containes previous numeric
      value in valid memo type range.

  * src/rdd/wafunc.c
  * src/vm/hvm.c
  * src/vm/memvars.c
    * clear passed item before RTE when accessed memvar or field does not
      exists

  * src/vm/hashfunc.c
    ! set default value before decoding 2-nd logical parameter in
      hb_HAutoAdd() function. It fixes ambiguity reported by Mindaugas.
