Really? So when I compile my application on a 32-bit Linux box and then try to run it on a 64-bit Linux box, you're not
going to overrun my buffer when CMSG_SPACE led me to allocate an insufficient amount of memory needed to account for
padding on the 64-bit platform?
By the way, FreeBSD, Mac OS X, and Solaris all behave as I described, so if you're happy with Linux behaving
differently, then I'll stop wasting bandwidth.
