Where ever a unit test is generating a buffer on the stack to send to a command processing function, this typically needs to be represented as a CFE_SB_Buffer_t* pointer, which by definition is supposed to be aligned to the worst-possible case, which may be greater than the alignment requirement of the actual command type. To avoid warnings when converting between types, use a union to ensure the stack object meets the alignment requirements for CFE_SB_Buffer_t. Furthermore, ensure all buffers instantiated on the stack are cleared (memset to 0) before operating on them or passing them to a CF function.
