The other objector to my claim that assert() may return has claimed
that implementations which have an assert() that can be made to return
should be ignored, despite the fact that AT&T UNIX 5.2.1 (and all releases
that I know of before it) has exactly this behavior.  Dave has repeatedly
stated that for all "real" UNIX's assert() never returns, without
accepting that this criteria is only true for some flavors of AIX and
BSD.  In any case, Dave is arguing against reality - the exception proves
the argument in this case, and the argument was that assert cannot be
relied on to always exit.  Providing the single counterexample of SCO
Xenix 2.2.3 (and of course, AT&T UNIX 5.2.1) disproves his statement
that assert() always exits.  [ And yes, he has made that claim, before
you state that this is a strawman. ]

Anyhow, this is getting old, and has long strayed away from the original
topic, which was to be careful of unexpected returns.
