If 'Init(a)' fails, then we go to 'Free(d)'? I'm sure that you can make it work, somehow. My point is that error handling is not that hard: if some 'allocate' fails we go to the 'unallocate' of the previous one. If you follow this rule, you should have correct code. If you try to get 'clever' about it, that's when mistakes slip in. Mistakes in error handling suck.
