Since you seem to have mastered the Standard far beyond what I managed,
would you mind explaining why the behavior is indeed undefined in the
cases discussed above?  I read the relevant sections over and over for
at least an hour and couldn't be convinced by either conclusion (defined
or undefined): I found half a dozen potential "undefined behavior"
related to "++", assignments and sequence points, but no one is obvious
here.

In other words, are you positive that CIL is not wrong here, or do we
indeed have a bug?

Thanks in advance.
