In what follows the term "Solaris" is probably wider than that. A better reading might turn out to be: "OSes and/or architectures in which multibyte operations (e.g. assign a 16-bit quantity) require a multibyte alignment (e.g. word, doubleword, etc)."
So understand my use of the word "Solaris" as a shorthand for that! Firstly: a general query to all: Have any "Solaris" users successfully run "ipctest" (under "lib/clplumbing")? Success/failure? For me, it fails, as the client is trying to write "String-2". After much tedious insertion of debugging statements, I have pinned it down. The "client" process of ipctest crashes in "socket_resume_io_write()" at the statement: head->msg_len = msg->msg_len Sure enough "head", on this occasion, is not cleanly aligned for an "int". (I suspect that there will also be similar assignments with similar problems: for instance I see one in the line following the one above!) Further when I run this on Linux (although "Intel" might be a better technical interpretation) all is well: these unaligned assignments are still present, but work fine. Secondly: a specific query to the developers: Could you confirm that the above analysis is reasonable? If so, how do we set about addressing this problem, and its instances? Should we be using "memcpy" for such instances? -- : David Lee I.T.
