 Message        <Context> the address "<expr>" has alignment of
                <align> which is less than the alignment requirements
                of the pointer type it is cast to.  Dereferencing the
                resulting pointer may cause an alignment fault.

 Description    The compiler has detected a situation where an
                address is being cast to a pointer type with a
                greater alignment requirement than the type of the
                address expression implies.  A later dereference of
                this pointer type value could cause an alignment
                fault.

 User Action    There are a number of possible actions.  The best is
                to correct the condition that is causing the source
                to have the wrong alignment, as access to an
                unaligned data structure involves additional run-time
                overhead.  Other options would be to change the type
                of the pointer used in the cast such that its
                referenced type has the __unaligned type qualifier,
                or use the compiler option that tells the compiler to
                assume all pointer references are unaligned.  It is
                also possible to cast the address expression to (void
                *) before casting it to the specified type to silence
                this message.  However, that solution will not
                correct any unaligned access.
