NUMBER:  153

  ERROR CODE:  S

  MESSAGE TEXT:  Allocatable array or pointer is not allocated

  EXPLANATION:  A Fortran 90 allocatable array or pointer must
  already be allocated when you attempt to deallocate it.  You must
  allocate the array or pointer before it can again be deallocated.

  This error is not returned by IOSTAT.  However, this error can be
  returned by STAT in a DEALLOCATE statement.
