buffer

size_t CORE_message_queue_Buffer::buffer[RTEMS_ZERO_LENGTH_ARRAY]

This member contains the actual message.

This is a zero-length array since the maximum message size is defined by the user. Use a size_t array to make sure that the member offset is at the structure end. This enables a more efficient memcpy() on 64-bit targets and makes it easier to inspect the message buffers with a debugger.
