Yes, I did. And I agree that can fix it. I didn't post those details,
but I came to the same conclusion as you did about the likely result of
using assignment. But I claim that the actual argument case can cause
crashes and other "havoc" in code that the standard appears to claim is
standard-conforming and *NOT* processor-dependent. In particular, the
bit about the result having the same value as E is stated as an absolute
- not a processor dependence.

And no, I don't think the authors of the standard consciously thought
about such things. Rather the opposite, I think such matters were
completely overlooked in writing the simplistic words that Brooks cited.
