oh, it was my mistake. alloca behavior is completely defined by it's generic implementation:
allocaBytes :: Int -> (Ptr a -> IO b) -> IO b allocaBytes size = bracket (mallocBytes size) free
although GHC implementation is much more efficient
That is, it is not a good idea to use 'allocaBytes n return' in order to carry a pointer of an allocated piece of memory out of the inner action.
