Message        volatile access appears unaligned, but must be
                aligned at run-time to ensure atomicity and byte
                granularity

 Description    The compiler has detected an unaligned access to a
                volatile variable.  In order to meet atomicity and
                granularity requirements of volatile, the access will
                be done using an aligned instruction.  This may cause
                an alignment fault at runtime if the access is
                unaligned.

 User Action    Make sure volatile objects are aligned on a natural
                boundary.
