I agree.  Except for some exotic architectures, and looking only at the "sensible" case where the two types have the same alignment and are probably just declaring the same data members in the same order, the reinterpret_cast should give the same address.

FWIW, the code base in question is currently compiled under Microsoft VS2008, and will soon move to VS2010.  And contains reinterpret_cast calls.  I'm replacing them with something tamer, as well as making sure subsequent use of the idiom is more formalized.

Defining a cisam explicitly indicates something that needs to be tested.  Having random casts throughout the code is always a wildcard.
