  26. According to the april draft working paper for the ISO/ANSI
  27. standardization, ostrstream uses new[] to allocate memory (unless
  28. you supply it's strstreambuf with a different allocationfunction, which
  29. in this example is not the case).
  30. So you should use delete [] p to free it.
  31.  
  32. [  By the way, the declaration of buf should be:
  33.     ostrstream buf;  ]
