Reading clause 1.9/14 of the C++0x draft. There I find:

Every value computation and side effect associated with a full-expression is sequenced before every value computation and side effect associated with the next full-expression to be evaluated.8)

And the footnote 8 says

8) As specified in 12.2, after a full-expression is evaluated, a sequence of zero or more invocations of destructor functions for temporary objects takes place, usually in reverse order of the construction of each temporary object.

What does it mean by “usually”? I thought the reverse order of destruction was the rule.
