解决cast from ‘char*’ to ‘char**’ increases required alignment of target type [-Werror=cast-align]

 cast from ‘char*’ to ‘char**’ increases required alignment of target type [-Werror=cast-align]

如#define NEXT(t)  ((char **)(t))[nextCol]

改由memcpy替换。

如

  NEXT (tuple) = tuple + tupleLen;–>

  char* pCharTemp = tuple + tupleLen;
  memcpy(tuple + nextCol, &pCharTemp, sizeof(char*));
  tuple += tupleLen;
